I wouldn't take this comment as anything but an anecdote. This is how some homeless people can be, so the take away is that the homelessness problem cannot be completely solved with housing. Some people are just cripplingly dysfunctional. They need more than housing, they need care takers. Just handing out keys to an apartment next to families to a dysfunctional drug addict who will smoke, vandalize and play loud music at night is not fair to the neighbors. These are normal middle-class people complaining, not some billionaire who can't stand the sight of a peasant lol.
