That's not the point, because the sim is not meant to train psychological skills, it is meant to train one's operational skills.
You're conflating unrelated things here. Granted, the sim environment will help you learn the skills for operating a given platform. But if this is a serious challenge to someone, then perhaps trading is not the field they should be in. Successful trading, though - which you include as soon as you mention "consistent results" - is a non-starter. Actual fills, price discovery, reasonable position sizing (and paying the costs of not doing so), confidence in trades vs. the commitment of capital, risk tolerance, endless other things
in addition to the psychological impact of placing real money at risk are things that no simulator can teach you. In fact, after a certain point, staying in a sim environment begins to damage your learning process: you're overfitting. Learning the skill of playing the sim game - which only resembles real trading superficially.
If a wannabe trader can't obtain consistent results on a simulator, why the hell would they be able to do that in a real live market? The thing most people get wrong is that you shouldn't try to train all the skills necessary for trading at once (i.e.: jumping straight into a real account).
"Try[ing] to train all the skills necessary for trading at once" is a strawman. One that has nothing to do with a sim account vs. a real one. If someone doesn't know how to learn, then that's the problem they need to resolve regardless of the environment they're in.
As to "jumping straight into a real account" - I see the value of making even a single real trade as being qualitatively higher, by orders of magnitude, than playing endless fake games. Putting a hundred bucks into an account and making penny trades against it will teach real lessons; learning to game the inefficiencies in a toy system (which you will
inevitably skew toward doing as you play one) will teach you the wrong ones.
Once you actually have a grasp on a given strategy, which you apply on the simulator in a disciplined manner and generate consistent profits, then you are ready to step up your game and go into real trading. Otherwise it'd be like trying to learn how to fight by picking a fight with a seasoned MMA athlete. First you master the basics, the you move into more challenging stuff.
What you're proposing is playing UFC Undusputed 3 "until you're ready" to fight that MMA athlete. That may be a good route to experiencing some surprising and unpleasant sensations along with large hospital bills, but it will not get you even an inch toward winning.
