Yes, we could have Al Gore selling unobtainium futures at $Trillions of personal profit and bribing fellow Dems to invoke eminent domain. Then the closing shows the big government sending men with guns to take away their home tree and imprisoning or killing those who resist big government.
Your novel take reminded me that Alex Jones saw the movie and kinda reviewed it on his radio program on Sunday. Alex is so unpredictable, I can imagine him loving it or despising it. He came down against it for its anti-American military, anti-development message! First time I'd heard that angle!
To summarize and paraphrase, he said what the Corporation was doing was flat wrong, but at least they were being "honest" in their theft by gambling that if the Navi could beat them in their big land grab, they could keep it and toss 'em off the planet.
But he said the Global Eites and Al Gore-types would have been much worse than the Corporation. The Elites would have sent only Avatars to Pandora, ingratiated themselves to the natives, then play the Save the Environment/Save Pandora card by saying the Na'vi were hurting the planet! Yes! And that to save Eywa, all the natives would have to agree to move onto reservations!
Once that was accomplished, then the Elites would send down the military, and the dozers, and the processors to mine and refine Unobtainium for themselves and shoot any natives that left the reservations!
I admit, that was a plan that left my head swimming!
