In Austin Texas when they legalized urban camping the short term effect was the homeless shelters and transitional housing programs cleared out in favor of camping in the posh downtown parks. There was a sudden increase in young rastafarian looking white kids living on the streets. When the ban was reinstated all those newcomers just melted away to wherever they came from.

Didn't seem like that bad of a life while it lasted, being in the tourist areas crime was never bad enough to be afraid for your safety, you had bleeding heart church groups that would regularly come by the camps to hand out food and clothing. All the while you can sell and doing drugs in the open.
