I'm not sure building a ghetto is the right answer. Whats stopping anyone from claiming a 10x10? Can I claim one? You're grossly oversimplifying the issue.
How is this a ghetto? This is housing that is more spacious than my dorm room. The current situation is accepting a ghetto to exist on the sidewalks where there is no plumbing or services or shelter or a lock or any semblance of safety.
It would be better if we could have decentralized housing for the homeless such that they are welcomed into more affluent communities and their financial status can be kept private. This is obviously more expensive.
Its not an easy problem to solve.
