In case you don't know, one of the reasons that some chronically homeless people don't have healthcare is that many don't bother to get it. There's guy in my neighborhood that told me he hasn't gone (but probably should go) to our local government to get his $100-ish/month, food stamps, and healthcare. Also, he ends up in a local emergency room because someone calls an ambulance when he's drunk, passed, and shaking out on the sidewalk. I've called an ambulance a few times for people in that state myself. He also ends up in the emergency room because he routinely gets assaulted while sleeping on the street because there's are not enough shelters for him.
