Everyone's already covered the issue of MC being shit at selling his skills, so there's no need to go into that.
The bigger issue, to me, is the reason he's doing this. Essentially, he's forcing his own rationale on the world. Normally, that's fine because that's how common sense breaking works.
But Hiroki knows essentially nothing about the world, so it's awfully pretentious and arrogant to claim he knows better than the common sense of the world. If it were a normal gamer, they'd assume the game was balanced differently and that his distribution DOES suck. In which case, back to the argument about selling his healing skill instead of evasion.
