guys that have spent 20k on a single piece of gear simply would laugh at you and tell you why it cant be done.
People that have spent 20k on a piece of gear follow the users' demand, though.
they also dont really care about the miners the miners dont have a vote if the dev's around telling people they can stake more and earn more this new way.
Well, miners shouldn't have a greater vote than regulars users generally, but in Ethereum it really doesn't matter. It suffers from far worse centralizing-kind of issues such as the dev team affects a lot as you said, there's a tendency towards PoS; lots of coins are also pre-mined.
I'm sure if Satoshi where around he would advocate a new system that advocates better decentralization but by his design he wouldn't have much say in it except a voice of reason.
What's wrong with the current system? I'm sure the reason he left was to avoid having a central point of Vitalik.
