Many crypto
graphy books will include a brief mention of "Rubber-hose cryptanalysis", pointing out the gap between theoretically sound crypto-systems and realpolitik. Everyone in the cryptography community knows that, no mater how secure your system, if a powerful state actor really wants to get you, they will.
It's surprising to me that anyone taking blockchain technologies seriously for "standing up to power" fails to recognize some basic realities of how power works in practice.
Blockchain is an obstacle to no real power, since real power does not care if some external source disagrees with it. There is no dictator that is going to say "damn, got me with that blockchain stuff *sigh* you win", they'll just torture you until you agree that you don't see anything troublesome in the ledger either.
As we've seen from cryptocurrencies rampant use in scams and ransomware it is absolutely impotent in the face of real corruption and power.
Ironically for crypto to work at all for these idyllic cases it requires a remarkably stable civil society, in which case a piece of paper in the public square works as well.
