"Open source plays no fundamental role in anarcho-capitalism and other liberal movements"
I see this all the time in the inability of the Bitcoin community to grapple with some of the thorny issues surrounding the fact that Bitcoin development is, fundamentally, an open-source project...
And like any open-source project, the development winds up being sort of "anarcho-communist" in practice. We all get together, "do as each according to our ability", and arrive at a consensus on decisions. Nobody "owns" this. It's Zucotti Park in cyberspace.
Bitcoin _itself_ on the other hand is the most real manifestation of an anarcho-capitalist economic system that was ever invented.
Bitcoiners who don't understand this dialectic wind up getting forced into this sort of "siege mentality", who's going to "win?" idea.
