I’m probably just ignorant, but aren’t these kind of the same thing?
The upshot of both seems to be “modernity is bad, the right way for humans to live is in some vastly simpler system characterized by either sustenance farming, shepherding, and/or hunting & gathering”.
I can’t speak for any indigneous people at all, but based on what I heard, North American, indigneous people, back before the US had stolen their land and committed numerous atrocities and genocides against them, had novel and complex forms of agriculture and civilization. calling them anprim for using different agricultural and productive practices would be like calling a french person an anprim for making bread differently.
