Biological needs are a fact of life, its not something farmers invented so people would buy their food.

At least if we're talking about the US (and probably EU as well), it isn't the choice between life and death. Anyone can go be homeless in California and get a couple hundred a month in food stamps and medicaid. Or panhandle a few hundred a month from tourists.

I agree you shouldn't literally die if you choose not to work in a first world country, but you should only receive the bare minimum to keep you alive (e.g. a tent, basic medical treatment and a steady diet of government cheese).
