It's a common misconception that humans without homes would be / are totally fine. Normal people who live in houses every day have no idea what living on the street does to someone psychologically. It's the jungle compared to our cushy lifestyles.

Sure, you can "survive", technically speaking. But living for days, weeks, years as an animal, fighting sometimes to the death for scraps, and god knows what else, it's definitely the comforts of friendship and human civility (that "money can't buy") that you're in the most need of.
