I think that's comparing apples to oranges. The $20,000 cost is merely the cost to provide housing. The $100,000 cost is the cost to provide court systems, mental health care, and physical health care. The problem is that the cost of housing is orthogonal to those issues. People who are in homes certainly commit crimes and go through the criminal justice system. They certainly need health care. That $100k figure may go down, perhaps even tremendously, but I suspect the real financial cost comparison isn't anywhere near so great. Otherwise, everyone would already be doing it.
