Any Libertarian arguments against Anarchy?

[Mr Khan]

I don't think people are quite understanding how anarchy would work. In essence, anarchy would be perfect Communism, requiring an equal-ish balance of all things for all people, and that there would be no need for political power because no-one would be in want, having their needs met by the perfect communal society where all people are as siblings

It's much more utopian than libertarianism, which advocates a state-of-nature system with the most minor of implications in place to keep it from becoming chaotic (libertarianism having different beliefs about where human nature goes wrong) Libertarianism is more realistic, but still utopian to the point of unfeasibility.
