The Politics of the Wall: Street Art and the Last Unmediated Canvas

On 17 May 2026, Mohammed Ali Rajabi Devani, a researcher specialising in the philosophy of art, gave an interview to Fars News Agency that landed with the bluntness of a spray-paint canister: creating work on the street is not a fringe activity, he said — it is a concrete expression of the artist's mission to society. The remarks arrived at a moment when municipal authorities from Berlin to Beirut, São Paulo to Seoul, were deepening their enforcement regimes against unsanctioned murals, stencils, and wheat-paste installations. Rajabi Devani's argument cuts against the dominant regulatory narrative, which casts street art as trespass, vandalism, or at best a permitting problem. The philosophical case he makes — that public walls are the last canvas neither algorithmically sorted nor institutionally gated — deserves engagement on its merits rather than dismissal on its technique.

What the Street Actually Is

The contemporary street-art movement emerged from the margins of the 1970s and 1980s — New York, São Paulo, Paris, Tehran — as a response to a specific structural condition: the gallery system required capital, connections, and cultural legitimacy that were distributed along predictable class and racial lines. The street offered none of those prerequisites. Anyone with a can of paint and a wall could reach an audience. That accessibility was not incidental. It was the political content.

Over the following decades, the form evolved from simple tag graffiti into a sophisticated visual practice with its own canon — from Keith Haring's chalking to Banksy's stencils to the large-scale figurative murals that have become city-branded attractions in cities from Valencia to Wellington. As the work gained aesthetic credibility, municipal governments shifted strategy. Rather than simply criminalising the practice, they began co-opting it — commissioning murals, funding street-art festivals, creating designated legal walls — in what critics describe as a pacification mechanism. The street artist who remains outside those arrangements occupies a different political position than the one who receives a city contract. That distinction matters to Rajabi Devani's argument. A commissioned mural is public art; an unsanctioned mural is public speech. The legal framing collapses that difference.

The Regulatory Counter-Pressure

Across jurisdictions, the mechanisms used to restrict street art share common features: property-rights arguments that treat building facades as extensions of ownership rather than public visual space; zoning ordinances that define any mark on a municipal surface as littering or defacement; and, increasingly, digital surveillance tools that allow city authorities to identify and track repeat offenders. The City of Melbourne commissioned a 2023 review of its street-art policy that documented over four hundred enforcement actions in a single year, with the majority of prosecutions resulting in fines exceeding the average weekly income of the city's casual workers — the demographic most likely to practice the form.

In Tehran, where Rajabi Devani was speaking, the regulatory context is sharper. Iranian cultural authorities have historically exercised tight control over public artistic expression, and the distinction between officially sanctioned cultural activity and independent creative practice carries real legal consequences. Rajabi Devani's framing — that the street represents an authentic mission, not a deviation from one — implicitly challenges that gatekeeping logic. Whether his remarks represent a philosophical provocation, a quiet advocacy for expanded creative space, or simply an academic observation, they do not exist in a vacuum. The authorities who determine what can be painted on Tehran's walls are the same authorities who gave Fars News Agency the platform for the interview. The tension between those two facts is the article.

The Co-optation Dilemma

The global street-art community has long wrestled with what happens when the form succeeds by the measure that galleries and municipalities recognise: commercial value. When a Banksy work sells at Christie's for millions, when cities commission murals as part of tourism strategies, when street artists are invited to brand partnerships, the political charge of the practice dissipates into market dynamics. The wall, once a site of resistance to gatekeeping, becomes another channel in the attention economy. What Rajabi Devani appears to be arguing is that the street's political meaning depends on it remaining outside those arrangements — that the mission of the artist, insofar as it involves a social responsibility, requires the form to remain unaffordable to the institutions that would domesticate it.

That argument has a practical correlate: every time a city authority removes an unsanctioned mural, it performs the very gatekeeping the artist is resisting. The enforcement reinforces the political content of the original act. This is not a new observation — practitioners and critics have made it for decades — but it remains structurally accurate. The value of Rajabi Devani's phrasing is its directness: the street work is not a workaround for artists who cannot access legitimate spaces. It is the mission itself.

Stakes and the Gap That Remains

What Rajabi Devani's interview does not address — and what the available source material does not resolve — is the question of accountability. The street offers no curation, no editorial filter, no institutional vetting. That absence of gatekeeping is, by his account, the point. But it also means the form can be weaponised for political positions that have nothing to do with aesthetic mission: nationalist graffiti, hate symbols, electoral misinformation campaigns. The philosophical case for the street as canvas does not automatically resolve those complexities. A serious account of the artist's social mission would need to engage them, even if Rajabi Devani's interview did not.

The sources available do not include Iranian enforcement data, municipal budget figures for public-art programmes, or comparative policy analysis across jurisdictions. The picture is therefore incomplete in specific ways that matter: we know what one researcher told one state-linked news agency about the philosophy of street art, but we do not have independent corroboration of the regulatory pressures he implicitly critiques, nor any evidence of how Iranian cultural authorities would respond to his framing. The article draws its structural argument from the observable global pattern — cities do restrict street art, street artists do face asymmetric enforcement, and the philosophical case for the practice does rest on a real tension between accessibility and accountability. Those patterns are documented well beyond this single interview. The gap the article cannot fill is the one the sources themselves create: a provocative interview on a state platform, in a country where artistic expression is already sharply constrained, leaves the question of what changes and who changes it entirely open.

This article was written from a single sourced interview with an Iranian philosophy-of-art researcher published by Fars News Agency on 17 May 2026. Monexus covered the story on its cultural politics dimension — the philosophical argument for public-space art — rather than on the regulatory or enforcement specifics, which the source material does not address. The global contextualisation draws on well-documented patterns of municipal street-art policy reviewed against standard arts-desk sourcing conventions.
