I think current games have already disproved that though. There are many games that while the may not specifically have a "skip" button, do have the ability to change the difficulty setting on the fly. If your argument was to hold true, then these games should have conditioned people to the point where the majority of people play on the easiest setting possible.
That still doesn't change the fact that your game play is unchanged. Unless you can demonstratively prove that having that easy setting has diminished your ability to play the game, then what is the issue?
