Most cities do prohibit property owners from storing their cars in an unsightly manner (say, on cinder blocks in the front yard), or from parking too many cars on the public street in front of their homes. Fair enough. Gun owners will have to accept laws against leaving nonfunctional guns strewn about their front yard, and they will not be allowed to leave excessive numbers of guns on the street. (Anti-gun groups frequently complain that there are “too many guns on the street.”)
