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
Ok, then i don't understand your sentences:
The would-be miner says about switching to a halving-free version of Bitcoin, which is quite the opposite of the total block reward cancellation you mention. The idea of 21 million coin limit may have served to boost the Bitcoin usage initially, but it will ultimately and inevitably turn it into a Ponzi.
That sounds like you think the cap will turn it into a ponzi and a halving free version would be better.
