>>5994133FWIW, in my city (Europe, with plenty of old, delicately decorated buildings), most of the street art is boring, repetitive, visually noisy, and people are heavily fighting against it (I walk a lot, so I definitely see walls being repainted weeks after weeks).
Regardless of what one think about the artistic aspects, or various skills involved, street art most often as a complete disregard for other people's wills. Same thing as repeatedly playing any kind of loud music in a populated area. Would you like to hear Mr. Bieber yelling Baby, Baby every day from your place of residence? Or to read women talking about their menopaused vaginas on the walls (they really do it here, so classy)?
In case this had never been brought to your attention before, I encourage you to have a look at
