1. claiming that the medical technology is "dubious" is a way of rigging the argument in your favor. There is nothing in the movie to indicate that the procedure wouldn't work as advertised. 2. Self-determination and sovereignty aren't being threatened here, PROPERTY is. The Baku would have simply been relocated to have sovereignty and self-determination on a different planet, they would have remained independent and sovereign, it wasn't an issue of conquest. So the "values clash" you refer to is actually that of the property rights of a few vs. the vastly greater good of the many. 3 the "Baku weren't asked" argument is one that gets brought up a lot, but it's kind of a silly one. There is a point in this movie when they realize exactly why they are being faced with removal, and they give no indication that they would consider doing so. The argument is basically a technicality-yes, there was never a point where Dougherty went down to the planet and directly asked "would you voluntarily relocate so that we can get this resource? We will find you a new planet and give you compensation." It is however, pretty clear from the Baku attitude in the movie that they would have said no.
