It's like taking certain types of painkillers that gets rid of the pain - you don't feel it anymore, but it is still there hidden from you. The thing causing it is still there as well. We need the anti-inflammatory equivalent of dealing with homelessness.

You can't have homeless sleeping on benches, it looks bad and scares away the touri$t$... real estate agencies probably agree.

then we shall sit on the floor

there are places where sitting on the floor is forbidden, like big train stations in germany. I think its only houserules, but security can kick you out anyway.

People in my neighborhood fuck up the benches. Light them on fire, or break them etc
