Giving these people a choice does not include shoving them off the land with bulldozers by people who don't even have any legal claim to that land.
In the book Monument that I referred to in an earlier post, a man crashlands a spaceship on a primitive planet, and lives with the natives for the rest of his life. Realizing that the planet would be attractive to those wanting its resources, he gives the natives detailed training to deal with the inevitable claimants, a legacy that will be passed on after he dies.
Legal training.
