Bitcoin will have endless emission regadless, we do not know what the value of transaction fees is going to be, it could be greater than the current block rewards and thus more hashrate could be running at a profit then.
Paying transactions fees is vastly different to an endless emission.
If the rewards from fees are not large enough to keep enough hashrate securing the network, then everyone who owns only Bitcoin will get 100% poorer.
I don't disagree, but that doesn't change any of the points I made above.
The outcome is far from being the same, one main point of strength of Bitcoin is its finite supply, raising the supply past 21M even if it was 1 coin a year will make the supply infinite just like all the fiat currencies, the economical difference between that and circulating a tiny portion of BTC from hodlers to miners is entirely different.
It is no different for the users. The whole point of a fixed supply is to stop your holdings being diluted by inflation and losing value. If you start taking x% from everyone, the same thing happens.
If I have $100 and you take 1% of it, my money is now only worth 99% of what it was worth.
If I have $100 and you inflate the supply by 1%, my money is now only worth 99% of what it was worth.
There are other options beyond taxing everyone one or another, though, such as sufficient on chain fees or merged mining.
