No, I don't think I did miss the point.
Players, IME, don't want to lose their autonomy to arbitrary die rolls. I am not talking about negative outcomes--lots of players are fine with them or actively love them (particularly angst-monkey gamers). At the very least, they accept it as part of the game.
I'm talking about autonomy. Having a PC be mind controlled is one of those things that remove player agency, and while most players are OK with it when it comes to control that stems from supernatural/supertech, having something completely mundane do it? No--I'd wager that most players aren't fine with it.
In D&D (and most other games), it would be considered bad GMing if you forced a player to be Intimidated by a glowering guard, or if one PC used Persuasion against another PC and the second PC was forced to acquiesce. It's OK to say "the guard is very intimidating" or "you find my argument very persuasive", and it's OK for the player to choose to follow along (consent is key!), but to force them?
Maybe some people are fine with that, but I for one consider that to be a very bad rule.
