It's not that much of a drive if one is looking for shortcuts to get what they want.You underestimate the drive of a completionist, especially considering all the routes are good.
Also, i think you're underestimating the amount of work it'd require to have things done your way. Some of the game events are mutually exclusive, and the story may rely on that to determine outcome(s). It's not just the matter of "removing the locks" but also adapting the code to, up to now, non-existent possibility that these locks are no longer present.
