This is the “noble savage myth” dressed up for modern times as the “ecologically noble savage myth”.

Colonialism is bad, yes.

But indigenous people didn’t “live in balance with nature”. Consider e.g. the massive ecological changes wrought by indigenous Australians, Easter Island, NZ Maori, etc. Megafauna extinction, massive deforestation, etc.

Human beings are human beings, regardless of their level of technological progress.

equating industrialization with techological process is pretty fuckin eurocentric of you.

Isn’t it, though? Would any of the technological - and often scientific - breakthroughs of the 20th and 21st centuries have been possible without industrialisation?

since a counterfactual can’t be proven, we will probably never know

Okay, but we can say with confidence that they all did require prior industrialisation in the way they panned out, and also, have never happened in any preindustrial society. That’s at least a solid hint.
