When did I agree to be in this world with everyone else? I am free to go off and live my own private life without being part of this "global community" if I choose.
This just doesn't seem too completely unattainable to me. The average able-bodied person, properly motivated and living frugally, should be able to secure a few acres over one or two summers, easily.
... Unless you're talking about true "Swiss Family Robinson" style independence from any and all societal benefit or influence. Because then, yeah, that is pretty much not possible any more. Finding someplace a little out of the way, and "living off the land" in relative peace, however - that remains quite attainable.
