You can always choose to grow your own food, fish or hunt. In nearly all US States you can still legally do that. Especially when it comes to non-incorporated/rural areas across the country, which ALL states still have. Might be different if you live the city life though.
Although it still costs money and takes time growing food. Same goes for fishing and hunting. Nothing is really "free" afterall. There are resources needed to do just about anything.
Rust belt anon btw.
