TL;DR: The guy describes how economy should work from his point of view, then says how it actually works and makes a statement that "something is wrong with the economy" instead of revisiting his own ideals.
My opinion is this: Bitcoin enables exchange of things outside any particular monopoly of law and violence. Chinese guy can buy something from Brazilian guy for bitcoins without asking permission from anyone. Is it bad or is it good? For these two guys everything is okay - they get what they want. Everyone else? Does not really matter because they cannot do anything about it. Even if it is awful and immoral from your point of view, it does not give you power to interfere: these guys are somewhere on the internet, you cannot easily come and stop them. Whether you like it or not, Bitcoin payments approximate mythical "free market" as close as possible. You can reason about trade on this market in purely economical terms without mixing it with politics (because your political opinion is very hard to enforce). So you either focus on what other people genuinely want, or you expose your egoism by pointlessly telling everyone what's your opinion about someone else's transaction.
