majority of ppl voted for some party, a party that gave consent to place/allow billboards, so indirectly, you gave consent. In the graffity's case - even the ruling party didn't gave consent, it's that they don't have resources to penalize and clean this mess
That implies that there was a party available that would ban billboards. There isn't, so graffiti is a way of actually taking back agency over our public spaces by underrepresented counterculture. Deal with it.
Most clasic graffiti to me look like trash left on the street, it doesn't convey the 'taking back of public space'. I like some graffiti concepts like in Berlin where ppl pay some artists to paint something over their building or some cool looking art on walls even when it's illegal/not approved (but would like to just go the approval way, or push for adding laws for such cases). But in the case of those random words/letters that maybe do have a meaning for some ppl - those are perceived by a lot of ppl just like trash, not a counterculture. Related to billboards- there are many places where cities do have a design code that basically forbids most of billboard types, esp in city center and it's not like you can't create your own party to push for this idea. If you don't gain votes, that means ppl are ok with billboards
