But the point of "living in the forrest is not an option" isn't that the person in question is incapable of surviving there. It is that the society claims ownership of the forrest an will punish you for trying to live there. I mean, try sleeping in your own car in California, or some other US states...
That's just the nature of almost any society: they are actively hostile towards such outliers.
To be fair, this philosophical discussion originated in the time of Locke and Hobbes, and back then it was far more viable to go off and live in a forest, especially if you went to America to do it.
the societies that grew yes.. there were many others that died. Most of the major countries recognized today in the West were originally warlike and held captives institutionally.
