Why the Avatars should not have been made

Someone has probably written a fanfic about it, but it still makes it a lot less plausible even if it did work in the story.

The....what, four hundred odd humans at Hell's Gate can't destroy an entire planet/moon's eco-system. And they've only got a limited number of people, the plant itself would need supplies - granted, in the movie they've just been restocked, but if the Na'vi banded together and fought back, the humans probably wouldn't be able to hold out for that long, or else be utterly restricted to being indoors. Ammo and weaponry would rapidly start to run out, as would trained people.

Should an open battle occur, the humans would probably win one, maybe two - after that, they'd just run out of people. It'd take the Na'vi longer than in canon, and with more fatalities, but there is nothing really to stop them kicking the humans off if they really banded together and worked at it . For similar reasons that the humans can't simply reclaim Pandora, as I believe you've argued before.
