"...our familiar/known culture view individual land ownership in a much different way than many NA? (Who could be territorial, but mostly as a collective ..."   I think you're probably right, particularly for those tribal groups who were still basically at the Neolithic hunter-gatherer stage of cultural development when the Europeans arrived.  For the settled agrarian groups (Hopi, Zuni) or the cultures that had urban architecture (Aztec, Maya, Inca), I would guess that they concepts of at least family ownership of real estate.  But we need a cultural anthropologist to weigh in here, to be sure.
