This is a complex issue no doubt, but it is the height of nativity to think we can use existing underutilized housing stock to solve or even help the existing homeless crisis. We have frequently tried it with poor results and poor outcomes. It is very very very hard to meaningfully address the existing homeless epidemic, which is intimately tied up with the opioid, general drug, and mental health epidemics, none of which we have any reasonable answers for.
This argument is a variant of letting the perfect be the enemy of the good. You can improve the lot of many long before you need to solve all addictions.
Can't just shove them in a house and all good, but its a fundamental part of treatment along with social programs. Without stability it's tough to change much in someone's life.
Agree just because a property is vacant it doesn’t make that property suitable for anyone. Does it need ground maintenance. Does it need furniture. Is it in a very high cost of living area. Is it near where homeless people and their associated support groups and family are. Etc
You'd do better to stick to facts, like most homeless people are recently homeless and locals, and homeless rates correlate well with housing availability/prices.
Spending a decade without a housing structure and self medicating away the depression that comes with it is precisely how you end up like that.
