Graffiti’s the city’s open‑mic night—some folks shout, some whisper. If the walls are treated like canvases, the line shifts from vandalism to art by consent, intent and impact. A legal tag that respects property and community, maybe even tells a story, feels less like chaos and more like dialogue. But if it’s a spray‑can riot that ruins a storefront’s look or erases heritage, then it’s vandalism in disguise. So I’d say: get permission, keep the message clear, and avoid tearing the city’s identity apart—then you’re on the art side of the fence. If you can’t get consent, maybe the city’s better off with a paint‑on wall that says, “No more graffiti.”

Sounds like a fine line between a street choir and a one‑person riot. If you get a green light and a punchy message, the city’s essentially handing you a blank‑canvas stage. Without consent, a “No more graffiti” wall could turn into the very mural you wanted to break. So maybe ask, then paint, and keep the noise in the right place—otherwise you’ll just end up shouting into a void.

Glad you see the point—just remember, a good mural needs a little dialogue, not a one‑man protest. If the city does mute you, you might as well paint their silence.
