I think that anarcho-capitalism, and to a lesser degree even libertarianism, is a fundamentally flawed philosophy because of it being against hierarchies that "suppress" their followers and in support of hierarchies that bolster them. In other words capital owners down playing the state and propping up "free market economics".

There's much changed since the inception but the core idea of anarchism is abolishing central powers (and single truth) in favor of their own homemade belief system where government has no power over them and can't enforce their laws, because, hey, they're (anarchists) moved away from main stream.

Communities with rules are not necessarily against the ideas of anarchism as long as participation in that community is voluntary.

Anarchism != chaos

That seems like an odd definition of anarchism that leads to confusion.

And anarcho-capitalism has nothing to do with anarchism since capitalism is a system of domination. It’s just rebranded laissez-faire capitalism.

"Anarcho"-Capitalism has nothing at all to do with the Anarchism of Pyotr Kropotkin, in the same way the "National Socialists" aren't actually Socialists.

Just a right wing group co-opting left wing terminology to try and give their abhorrent beliefs credence.
