I briefly looked at a cookbook for dumpster divers, it was in the form of a loose association of ingredients that complemented one another, and suggested cooking information for specific ingredients. It didn't give me any sort of dumpster diving enlightenment. I also looked briefly at small game hunting and fishing both of which seemed to indicate that you need licensing and might even have per expedition fees. (not to mention this might be rather time consuming, and eventually constitute work) I've not found or thought of any sane way to grow crops without land.
I'm not sure a life free from work, at the expense of replacing all animal products with yogurt, and effectively having no finished dishes, sounds appealing to me. It may be the seasonal work suggestion of >>5 would be a better suggestion. I thought for a moment that you might be able to go half-way between the homeless and leisure class routes, where you just have enough interest to generate a few grand a year for groceries, but apparently Roth IRAs are counted as assets for medicaid. I suppose you could still do this, but you would need a few thousand more a year to cover medical expenses. That'd be something like 100k-150k in savings, which ain't pocket change. Might as well buy a place to live at that point.
