OK, done. I'll read chapters 5-6 tonight too, I think, because chapters 1-4 are indeed very interesting.
You already gave a summary but for the benefit of those who missed it and need reminding: it's a very stark and well-evidenced piece showing that bitcoin is intrinsically linked with right-wing libertarian rhetoric. It's virtually impossible, according to the author, to find anything favourable written about bitcoin that does not take right-wing libertarian assumptions as its explicitly stated starting point, and this is true no matter what the claimed political leanings of the author.
In concrete terms, proponents take it as a given that governments form a tyranny, no matter the government's actual aims. Meanwhile, the very real tyranny created by allowing corporations to accumulate power without controls on that accumulation are either ignored or positively embraced.
