I think that many yearn for an idealized life in a small, relatively isolated community, low tech and free of fiat currency. They try to imagine workarounds for the fact that it's not actually currently possible in reality.

UBI, anarchism, antiwork and other radical ideas are proposed patches to the cold and lonely reality of modern metropolitan life. They would probably not work, but they are not really the point. The point is to imagine some escape from the current crushing system.
