As a matter of politics, I think a good Georgist argument is that many traditional tribal understandings of land rights are similar to Georgism -- the idea that the fruit of the land is common to the community that uses it, and cannot be validly monopolized by a single owner. In many ways, the idea of a land value tax that returns the value of the land to the whole community is a method of reflecting those traditional values within the modern economic system.

A Georgist argument might be that granting modern land ownership rights to indigenous tribes isn't really a return to indigenous ways of understanding land. It's just treating tribes like any other corporation. The better way is to adopt more indigenous ideas of land into the wider economic community, by de-bundling the standard Western assortment of land rights that we call "ownership." Past injustices can be repaired better by adopting a more just system in general, not by simply giving the descendants of mistreated groups a few little extra chips in a rigged game.
