It's not 51% of people, it's 51% of computing power, or 51% of stake if Ethereum ever switches to proof of stake. Ethereum runs by capitalistic power, not democratic power.
I don't know if there's any alternative to that; any such system is going to have some means of enforcing truth and power, and means of gaining or losing it.
Cryptocurrencies are not a way of escaping that fundamental fact. They shift where the power is. Having that alternative to current ledger and contract systems can be valuable to people in certain situations.
Thinking that Ethereum or Bitcoin or any blockchain tech escapes these fundamental power relationships is exactly the type of inanity that makes the tech seem unserious. It's a hype train, it's not true, but there is still the potential for value.
