Your explanation is wrong. Economic majority is represented by those, who are transferring btcs, e. g. doing business. Not just hodling - that doesn't create economy (not that it's wrong to hodl per se). Miners are rewarded by those who make transactions.
no
the block reward is the miners payment. and miners can accept or reject any transaction they like.
heck i can make a Tx that has a 2000btc fee. but it can be rejected for many reasons and has no way of swaying a miner to make protocol changes even if they accepted it.
peoples funds and network protocol are separate things.
also the fee does not mean anything. many pools have already made blocks this year with just 1tx (the block reward), many pools have already made blocks this year ignoring certain transactions that are bloated even with a higher fee..
