Libertarianism is just the point of attack for atomizing people economically from society.

Feminism is the point of attack for atomizing women from their families.

Atheism is the point of attack for atomizing people from their religious community.

Liberalism is the point of attack for atomizing society through legislation.

All these things weaken the bonds of a community and make it vulnerable while making the kool-aid drinkers feel empowered. The problem ironically enough, is that some of these same libertarian thinkers pointed out the importance of understanding the net effect of an economic policy, i.e. the broken window fallacy, the seen and the unseen, subsidies, etc.
