What is the safest way for a partially disabled person in the USA to use prison for food and shelter as an alternative to dying homeless in a gutter on a cold rainy night?

If you are set on this, then do crimes that, if successful, would improve your life.

Steal billions of dollars from bad corporations. Steal food to live, trespass to be in shelter.

Personally, I would try to go to the cheapest town and get on benefits. Each state has a really cheap place to exist. There are usually no jobs, but often friendly people.
