Don't miners control who is allowed to make transactions? Simple question really, considering theres a very small group of miners controlling the chain ATM.
Whats to stop them from being forced by the goverment to disallow certain transactions or just mining empty blocks to jack up the transaction price?
Or even worse, whats to stop a country like china from just investing massive ammounts of money into unbeatable mining pools and destroying every appearing coin that way?
Don't miners have way to much power in the current system? Especially since crypto is supposed to be decentralized
The stakeholders of bitcoin don't want miners to do that. If miners do that, the stakeholders (the people who are paying for the miners to mine) would change the rules. For example, they'd change the mining algorithm. That would turn the miners expensive ASICs into space heaters (a little faster).

The miners only have power because the people paying for their mining hardware and electricity like the job they're doing. If they don't provide the censorship resistance and forward progress without double spends that the stakeholders want, the rules will change.

Miners know this and such a scenario would cost them a huge amount of money, so they are strongly incentivized not to let it happen.
