Sure but white ownership did prevent the way they had been using the land before. I think the current understanding is that primitive people develop rights to some land via use. However I am not aware of a country that actually routinely affords them such rights. Brazil tries.

IRL primitive people have no rights and everwhere have been expropriated. Not sure who can be on their high horse about that.

To be clear Amerinds on the rez aren't primitive anything. That stopped a long time ago. They're just bums.
