Carcazoid, have you even watched the movie?
You only made a single point that that was not contradicted by the movie (we saw the full extent of baku 'power'; the federation has 2 legal legs to stand on and then some; it's near-certain the harvesting method will work) or was not an irrelevant value judgement:
The movie wanted to convey a situation like the trial of tears, etc. That's obvious.
What's also obvious is that it failed to do so. Equating an obvious eminent domain situation to the conquest of the amerindians is quite the straw-man.
