While indeed civilization came at a great cost to both human livelihood and the whole planet, and i agree that ideally it wouldn't exist, the fact is that it does exist and we can't change that. That makes it necessary for tribal societies to make great changes to adapt to the new conditions (environmental deterioration, unequal access to powerful technologies and, y'know, being permanently outnumbered by the sheer brute force of the mass agriculture-fed human stampedes), which in turn makes almost impossible for any human group to subsist in the long term in their pre-civilization or pre-contact with civilization state of social organization. That doesn't mean however that the tables can't be turned, the eurasian nomads ended or helped to end multiple empires throughout history for example, like the Huns against the Romans, or the Mapuche winning against both the most powerful empire in the continent, and then against the most powerful empire in the world at that moment in the Arauco War. What this teaches us is that alternative social organization models non-dependent on total domination of man over environment can subsist and even thrive in the face of confrontation with more civilized forces, but the path forward is not to stubbornly hold to the now impossible ideal of universally adopting an harmonious-yet-powerless lifestyle. The path forward is to strive to reach a Westphalian balance of power between so-called primitive societies and civilized ones, so that an alternative to our current predatory order can survive while it is still unclear if the path of civilized societies to some form of socialism and the end of their internal contradictions will ever come.
