Have a "free aisle" in grocery stores. Come and take as much textured soy protein, cooking oil, flour, salt, potatoes, powdered nonfat milk & wheat bread as you can carry. Everything else in the store - cash only, no welfare cards, food stamps.
Free food to survive but nothing but the basics.
I liked Larry Niven’s universe - dole yeast, free, just enough to keep you alive, didn’t taste good. Motivation to get a job to eat better.
