Actually upon further reading I realize that the author actually goes deeper into what I thought, so it's not nonsense, it's actually a simplified version of what I tried to write.
But I don't particularly like the whole "mass vs not mass" discussion as it's pointless
Well, the author did superbly better job of explaining anything to people that haven't graduated quantum mechanics than you did. That's something.
Recognizing correct analogies is not easy and it's insanely powerful educational tool.
