BUT if more and more miners join, doesn't that also mean that more and more users will also use sub 1 sat fee transactions which would make the miners' revenue from fees also go down?
¯\_(ツ)_/¯
The point is that bitcoin price is already way too high.
1 sat /vB is already a lot of money. 10x more than it was 5 years ago.
Allowing 0.5 sat/vB por example is just a basic adjustment.
