No, it's a philosophy meant to scare the players out of trying to break the game to their advantage.
I don't really see a difference between this and what I said. You're just spinning it more positively than I did.

Finding a trick that is always convenient should be evaluated against the narrative and suspension of disbelief, and based on that the group should either:
- agree that nobody uses the trick (it doesn't pass the narrative test and breaks suspension of disbelief, presumably a rules artifact/loophole)
- agree that everybody uses the trick (it makes narrative sense, so why should only the PC in the whole world have figured it out?)
This suggestion assumes a philosophy that not everyone shares. That was the point I was making in the post you quoted: not everyone ascribes to the what's good for the goose is good for the gander.
