1. To be clear, I'm not thinking of a 51% attack, I'm thinking of cyberattacks on the miners and exchanges, mining equipment seizures, international warrants etc. 2. I was wrong in my explanation, you're right that fiat is a (social/financial) technology and in principle crypto could be an alternative. What I was thinking of initially is that the problems of the finance system are social, not technological: the incentives in the current system (the rich keeping their richness at the expense of everyone else) are a social problem, which can't be fixed with technology. As long as the rich stay rich and powerful, they will control crypto just as well as they controlled gold and fiat before it. 3. ETH can do, what, 24 TPS? Right now there is no coin that can realistically compete with the global banking system, especially on the last mile. And I don't think PoW or PoSpace will ever get there. And PoStake doesn't seem like it has any real advantages over a trusted distributed DB, to be honest. 4. Those are quite noble goals. Probably a major difference of belief between us is that I don't believe any change towards decentralization can come from (computer) technology, I believe it must be a social movement with democratic power that moves things first and foremost - any kind of purely technological solution will easily be co-opted by the rich and powerful. In this way, crypto should look at what happened with the Internet itself, as Google and Facebook and others slowly absorbed it.
