Love won't feed you, or save you from trouble. Anyway, the problem with
#HousingFirst becomes much clearer when you imagine a hoard of slavering tax collectors wringing their hands together and declaring "Housing comes firrrrrst."
House is synonymous with prison, after all. Making sure the former does not become the latter is key, I think. When the homeless reject my amazing unbeatable deal to make them not-homeless, it might be my deal that's the problem. So most important is making it awesome to be homeless, or at least as awesome as possible. 90% of their problems come from people who are like "I want to make homeless people even more miserable" and doing just that.
Housing can come once you've punched those people in the face until they stop being dicks.
