I think you miss that switching to a non block halving version of bitcoin will effectively break the 21 million coin limit. Since the block halving is calculated so that at the end 21 Million coins came into existence. If no block halving would happen then bitcoins would be created indefinitely. That's the definition of stopping the coin limit
I guess you have to read my posts more carefully
If we were to cancel the halving, can we remove the 21mil hard cap as well?
The latter follows from the former
