This idea has nothing to do with the Gigabet thread. In Gigabet's thread, he said the gamble would not hurt you significantly, since it would bring you back down to the average stack size which still was threatening to the bigger stacks, but winning the gamble would bump you up to the point where you can start to bully as a big stack. Never did he suggest taking a risk that would bump you down to a critical state.

You are overthinking things. Being in the red zone may give you more +EV opertunities, but that does not mean it isn't better to have a big stack. A big stack that folds a hand has an expected stack size of however big his stack was, while a red zone stack that has to push the hand will still have an expected stack size of much less than the bigger stack. Even though the small stack took advantage of a +EV opertunity, it doesn't mean he has gained anything over the bigger stack.
