You can't loose what you don't own.
The indians did not have "land ownership". Claiming to own land is only something that started AFTER the settlers came.
(people forget, that the indians thought THEY were cheating the dutch by selling manhattan. In their mindset NO land can be owned.)
This is just more "pro-communist"/collective ownership disguised as something else bs.
They knew what territories were theres, and which were not, and who had hunting rights, or fishing rights, and who didn't.
I think folks are confusing precision land surveys with "ownership".
