I generally agree. I do have a question, though. Would it be this bad without the marketplaces? I had a sliver of hope for a small period of time that bitcoin would truly replace fiat currencies. And that ethereum could replace law. Both have failed to achieve their goal. Is it society’s fault or has the tech always been pointless? Are there meatspace things society could do like e.g. ban using dirty energy for mining, ban proof of work, some [thing] about regulating exchanges, etc.?

You underestimated both the number of problems solved and effort put into making those solutions. Law and Currency are extremely complex institutions that solve complex interlocking problems.

Replacing either one completely is probably impossible and any change to them will probably have to be iterative improvement, not replacement.

Can you write an ethereum contract that would ensure ethereum covered by it was not mined with dirty energy?
