All of us are born incredibly dependent on others.

"Others" as you use it is far too imprecise. A person is born dependent on his parents, who have an obligation to raise him once they've chosen to carry a child to term. That obligation does not extend to people that didn't make the choice to bring the child into the world.

Also, you're attacking a straw man. I'm not an anarchist.

Sustaining a rich and complicated society requires that people act as traders. That entails producing things that are valuable to others, in exchange for things that are valuable to you, quid pro quo. And that requires a government, whose sole duty is to retaliate against people that try to bypass that process by force or fraud. A market cannot exist without an objective arbiter that keeps the peace (which can only be accomplished by having a monopoly on force - private armies, courts, police forces would lead to war) and enforces laws.

Yes, that's the fundamentalist libertarian perspective. Like most fundamentalisms, it is hermetically sealed: you can never convince a Freudian it isn't all about sex, or a bible thumper that it isn't all about God's word.

I always find that a little depressing with libertarianism, as there's enough useful material there that I hate to see fanatics turning people off to it. There's a giant difference between "an important function of government is" and "government's sole duty is". The latter is appealing to people looking for simple answers to complicated problems, but is actively off-putting to everybody else.

I understand you don't think you're an anarchist, and, for a different reason, I'd even agree. I think the step-over-the-dying school of libertarianism would turn out, in practice, to be indistinguishable from the sort of chaos that people who don't know any actual anarchists think when they say "anarchy". (The interesting sorts of anarchism, like what the anarcho-syndicalists were pursuing, depend upon a human moral sense. Which, bringing this back, include compassion for the ill.)

The reason things will fall apart lies in another gap in your thinking. Parents are the most obvious thing a child depends upon. But try telling a teacher or a grandparent or a cop or a social worker or a neighbor or an aunt that they don't matter, that they don't have an impact on the kids they deal with. It takes, as they say, a village. Or, if you'd like a richer society, a lot more than that. You'll of course wave that away as inconsistent with your chosen theoretical framework. But that you can't perceive the value in something doesn't prove that it's valueless. It only shows you haven't bothered to really understand it.
