The key here is 'use'. Kant, while obviously not some gospel to be held to any form of authority, is making a point about differences in culture and sure, as you said, use. However, my point wasn't disputing usage at all. Living on it. Hunting on it. Working the land.

However no view exists in a vacuum, and I will indelibly view my example of a group of 4 as a valid statement, about the absurdities of 'walked on the land once in my life, to get to my summer/winter home', compared to some claims of a tribe of a few hundred people, somehow owning hundreds of millions of acres of land, just cause they walked on tiny parts of it to get to their seasonal homes.

So no, I don't see the relevance, because I'm not discussing the concepts therein directly.
