Can you clarify whether you're critcising the idea that a King's Indian player should attempt to get a King's Indian if white plays 1.c4/Nf3/g3 instead of 1.d4?
I was mostly responding to this line: "It's cool being able to play it against almost everything that isn't 1.e4," and also "Then ...Na6 against everything else." Maybe if you clarified your suggestions a bit more I wouldn't disagree with you (...Na6 is utterly useless against the Saemisch, for one), but it sounds like you're recommending playing a "system" instead of playing a complex opening system where every move by White might cause Black to re-evaluate where his pieces and pawns belong, and vice versa.

The King's Indian is a flexible opening, you don't need to play it sharp and tactically. It can be played moderately or very defensively depending on your style, or how you feel on the day.
Here is where I (and I'd think 99% of players stronger than myself) really disagree with you. First, playing "moderately or very defensively" is a recipe for disaster in chess in general, though certain types of positions are more forgiving of that kind of play than others. And while the King's Indian
is a very flexible opening and allows Black to play his first 5 moves against pretty much everything, he pays a very high price: White can get an enormous space advantage. In most variations, if Black doesn't play extremely energetically he will have nothing to compensate for this, and White will have a very easy to play and large advantage. Further, it's really White's decision to gain a lot of space or not, so whether Black is required to play aggressively is entirely out of his hands. Look at the Saemisch variation for one; there's a reason that sacrificing a pawn on move 6 or beginning rapid central and queenside counterplay with 6...Nc6, 7.Nge2 a6 8.Qd2 Rb8 are the most popular ways of playing.
Here's one game I've always liked; look at how hard Black has to play to strive for counterplay, eventually sacrificing a piece for a couple of pawns:
http://www.chessgames.com/perl/chessgame?gid=1070619. Even here White missed a win or two, but that isn't entirely the point. Black has to be prepared to play with extreme amounts of energy, dynamism, whatever you want to call it in the King's Indian. Notice that Black wasn't even facing threats on the kingside, but his severe lack of space was enough to mean that he was losing without drastic measures.
Not everyone can play like Fischer or Kasparov, and trying to play it "moderately or defensively" will just make you suffer without space, with a terrible bishop on g7, facing a mating attack down the h-file, penetration on the queenside, and sometimes all of the above. We all like to think that we can play like Tal or Kasparov, but any player should ask themselves: "Could I have timed 17...Nxe4 correctly, as Kasparov did against Bareev? Even when the resulting position was still better for White? Anyone can play ...Nxe4 when we see that it leads to advantage." If the answer is no, then the King's Indian probably isn't for you. And there's no shame in that, many of the world's best players throughout history have avoided the King's Indian.
Anyway I'm not going to belabor the point more. I'm actually working on a book from White's point of view (which may or may not ever be finished); if I complete it I'll just be able to refer to my book instead of trying to debate this point online. The King's Indian is a wonderful opening, but it shouldn't be played as a "system." If White plays very passively Black can get away with anything, but here White can grab a TON of space and have a long-enduring large advantage if Black doesn't find counterplay. White doesn't even need to play very sharply and attack down the h-file or anything like that, simply putting his pawns on c4, d4, and e4 is enough to require Black to play with great energy or suffer.
Okay /end tirade.
