You talk about humans like if they are old worn out machines or shoes, or babies are dumb and shit....you think the mentally ill and the addicted are what? Refuse? Trash?
They are frequently incapable of providing for themselves.
This statement is revealing of your entire societal worldview, BJ -- you've fallen victim to Western reductionism in this atomistic, hyper-individualistic perspective that you have for all things social / societal.
I'll remind that there's such a thing as *infrastructure*, which is *not* reducible to individual usage -- like PoFo itself -- because the costs of supplying to additional users is *negligible* once the infrastructure is installed.
The *point* of society isn't necessarily for everyone to be self-sufficient, because if we did that for *food production*, for example, everyone would be needlessly sacrificing a good chunk of their *lives* away instead of doing what we *do* do, which is industrialized, fuel-driven farms that provide to thousands and millions.
I don't think *anyone* 'provides' to themselves -- *I* certainly don't. Rather, people enter into *economic relationships* and get the wages / money they need to partake from *other* people's efforts. Your worldview, as stated, makes it sound as though you think we're all still living on family farms.
