Private Property is how. People don't own other people's property for abstract reasons like they joined a club that once painted graffiti on walls.
>“CAMP has had both written and verbal agreements/understandings with property owners and landlords regarding murals on Clarion Alley for 34, going on 35 years,” read a statement from Clarion Alley Mural Project.
If there was an agreement in place, property rights would protect the murals from vandalism by the property owners, not the other way 'round.
I think you should consider why you immediately, and incorrectly, jump to the defense of moneyed interests over artists and community organizations.
They claim to have arrangements with all property owners. Verbal arrangements are just as binding as written ones, though generally not a good idea as they are harder to prove.

Because property rights are good and allow for a functioning society.
Your opening statement here is pretty ridiculous I need to say. "Written agreements doesn't mean shit!" Then you just make up a scenario where the contract wouldn't hold up.
Asking "is it cool if I paint your wall?" more than three decades ago doesn't create a contract or protect the work.
I highly doubt that street artists made a legally binding agreement with the owners that protects the art for the simple reason that this would be a ridiculous encumbrance on the property that would be unacceptable to most sane people.
