This is exactly how I feel seeing the homeless camps in Austin. Primarily, the first question I had was: what happens when one homeless person wants to spot of another? Neither has a legal right to it; are we not encouraging interpersonal violence by refusing to enforce the property laws that separate us from the state of nature?
>my experience has been that most are not locals, despite what surveys say, because the surveys always rely on volunteered answers about origins, rather than proven identity
Right. Why would anyone tell a volunteer they're from out of town? Seems like the first rule of being homeless: get a story that appeals to people. "Born here and down on my luck" is much more compelling than "Where I came from is worse than this place so I hopped a ride here."
Basically, we can spend all the money in the world and build all the housing that people need, but the personal liberty that this country espouses -- personal liberty I agree with! -- means that no one is obligated to take it. There is already a myriad of excuses I hear in these threads for why the homeless don't go to the shelters, participate in the programs, etc. "They don't allow my dog." "They would make be get sober", etc. Until we accept that there is a significant population of unhoused that prefer it that way, and then decided what we want to do about that, all the little villages and things won't scratch the surface of the problem.
