My to-do/to-read list is too long already, but you are welcome to summarize the key idea(s).
But I don't really trust anthropological studies, I feel like they rely on guesswork too much.
Anyway, the argument is clear: #Free #markets do work and we know the theory behind it - economic calculation and distributed decision making. We also see it in practice: That's how you, for example, got a supercomputer in your pocket. It's also the only moral way, because it's voluntary and peaceful. (Any alternative is by definition based on violence.)
That's basically it. Case closed.
