I wish to propose a solution: A tax when you wish to add someone to your block list. $1 per person per door per year. Madison Square Garden is a popular spot and so serves lots of people and so has lots of doors so that business should, I think justifiably, pay more to block people than a single door hardware store. I think that this might be a decent solution because it is a modern analog of blocking people using low-tech methods: blocking people using human memory is costly and that cost is the natural means of limiting abuse and letting the person remain a member of society.
