This and that there is a hard upper limit on the amount of bitcoin available. There will be no QE of bitcoin.

until the miners are convinced otherwise

bit like the central banks

not at all like central banks because mining is decentralized. Besides, there are also users and merchants who are just as important and miners don’t dare pushing changes that nobody wants.

Do you realize that of miners decided to fork in favor of a model which is better fit them, there will be a shortage of block mining until the difficulty declines. Which means transactions would be frozen for around a month. I'm not sure users and merchands could stand that fight …

Some already did - bitcoin cash.

Rational miners realize that forcing a protocol change that isn’t acceptable to users or merchants will destroy valuation of the fork they choose to mine, so there is discebtive from such behavior.

But yes, if they do it anyway, there will be period with very slow blocks and that will hurt the project a lot but then difficulty will adjust downward.
