I don't think Saelorn is. I think she is only making the narrow claim that a system should not give a an incentive for making a particular choice if it wants to promote role-playing, since having a mechanical incentive to make a particular choice tends to discourage playing a character.
I hear this complaint a lot, and I don't quite get it. Its not like in old-school DnD, where you can get stuck with requirements by class with little or no input on how those will be adjudicated (and indeed, I've seen many vastly different interpretations of what counts as "lawful good" over the ....god help me...decades). In Fate, you get to pick/declare up front what your recurrent challenges and defining characteristics will be. So, if you don't want to face compels for stealing things...don't take an aspect that would be compelled that way. Essentially, Fate is asking you to tell me about your character upfront, and then reward you for playing that way...its got Role-playing rewards baked right into the system! You can even "self-compel" by offering one up to the DM, if they overlook the opportunity.
Now...the other part of the complaint which is..."I don't want to think about non-sim mechanics" (Fate points are no more "meta" than HP or XP). That, I get. That person likes what some would call "Actor" stance, and they don't like being drawn out of it...fine. No problem. But the idea that a mechanic that directly incentivizes you to play the character which you said you wanted to play somehow discouraging roleplaying....? Wut?
