Wow. As you did with the book, I stopped reading after the first analysis you made. So let's just focus on the first chapter, right? There, you called out on the writer to mix institutions with government and capitalism.

Yet it makes all the sense for me. In any country, the government enforces the market practices - may it be free or controlled - through its institutions. And the author criticizing both government and capitalism cause he is an anarcho-communist! He opposes the existence of both.

I hope it helps you understand the book a bit better. Cheers!
