as others have already addressed the headline "no those arent the same at all" issue, I'd like to be more specific: even the indigenous movements in the cultural zeitgeist that you might be thinking of aren't advocating for primitivism.

Saying "the indigenous people of this place managed its forests better and used practices that took settlers hundreds of years to rediscover", isn't advocating for a return to the pre-columbian indigenous societies, but at bare minimum a recognition that indigenous people are experts on their land and their management practices aren't primitive but actually quite sophisticated and serve important roles in cultivating pleasant, stable ecosystems.

That's just one example but the same principles apply in other realms as well, but have often been ignored by settlers due to their chauvinism.

Similarly, demanding their sovereignty be respected during planning of infrastructure that affects them, does not mean they are against building modern infrastructure, it means they want their sovereignty to be respected.
