Society should have no obligation to those who won't help themselves. We should aid those who can't help themselves.
the premise of this statement is inherently and fundamentally flawed, because it ignores the fact that "society" makes it impossible for someone to help themselves outside of the framework of "society" in the first place; for which you could make a very valid argument that it becomes society's duty to help everyone who is unwillingly a part of the system.
for example...
there is no fundamental right (human, national, or local) to decide to go "off grid" and fully revert to a pre-civilization state and live like a caveman, being a fully self-sustaining lone hunter-gatherer.
you might be able to get away with it for a time, even groups might be able to, but assuming the rest of the country still exists as it does today, sooner or later someone is going to get a bug up their ass about you being on their land, or some government agency is going to get shitty about you not paying taxes, or declare you a public health risk, or something... checking out of the human condition simply isn't an option.
