Earlier quoted context omitted.
I'm a little lost. What does ETH provide society if it's just another system for allowing 51% of people to screw over the 49% that dissent?
A system where it is not 0.1% of the people who are allowed to screw over 99.9% of the others? You argue for purity of a principle. Very few people actually care about such a notion. The majority has more practical concerns. The fact that a theft that would have made the whole currency seem insecure has been reversed was seen as a proof of solidity by many users.
The current system at least theoretically has democratic (or otherwise) control over who the 0.1% in power are. In a system like BTC or ETH it's just 'who has the most compute?' or in proof of stake, 'who's the richest?'
