Sounds like what in common parlance is called 'escapism' or 'escapist entertainment.' About right?
I've heard this argument before, and it doesn't hold water for me, because it blows a very small aspect of TTRPG rules out of all possible proportion.
The issue is that the gulf between player and character in a TTRPG is already so vast, that the ability to overcome that gap and achieve immersion cannot possibly be consistently, irretrievably foiled by something as obscure and trivial as a 'dissociated mechanic.' I mean, if you're trying to get under the exoskeleton of your Thri-Kreen character in Dark Sun - to achieve 'immersion' in the imagined role of a giant insect slowly cooking to death under the brutal heat of an alien sun - while sitting around a table in an air-conditioned FLGS, sipping cold mountain dew, eating twizzlers and rolling dice with your fellow gamer geeks, and you actually /do/ it, you have one kick-ass imagination. And to claim that you /cant/ do so if your ability to unleash a flurry of claw attacks is 1/encounter instead of not existing at all, is more than a little implausible. It's like the suspension of an ATV being wrecked because, between off-roading over huge rocks, it hit a small pothole on a short stretch of paved road.
This is not exactly the same thing, but it's related. People who write in genre fiction (of any kind) outside of the real world have to deal with the "suspension of disbelief" problem. And one of the first things I learned about it was that, generally, you can only take people outside their comfort zone once. Saying "this is a world where spies fight world-dominating secret organizations without mussing their suits" can get past people's filter without too much difficulty. But add in a talking animal for no reason, and you get people leaving the theater, saying it's "unbelievable".
You can only push people's immersion past a certain point, and it's different for everyone. So, yes, you can have people capable of accepting the hideous clawed monster, and then the "oh, btw, your attack power has charges" is too much for them. It's an emotional reason, but it's valid. It's not hypocritical, it's the way they honestly feel.
