> Usually buildings have private property owners. They agree to putting a bill board on their wall or they don’t. And yet if I agree to have someone stand on my property shouting insults at passers-by I'll get a visit from the police soon enough. This issue isn't as black and white as you make it out to be. Just because the owner of the building the billboard is attached to agrees to have it there doesn't mean no one else is affected. There's already limits to what you can put on a billboard. Banning billboards isn't some radical new category of thing. it's simply moving that threshold down to "you can put nothing on billboards"
