... it's factually wrong small tribes have long histories of trade and war with each other, way before agriculture showed up. ingroup x outgroup is so deeply ingrained into our psyche the idea that there ever was a tribe like that is simply ridiculous

Um yes this paragraph says bonds are strong within the group but if a tribe meets another group they fight... (or move on)

i'm trying not to be very dismissive/my usual self about this because the drive to project a conflictless past and use it as proof that a conflictless future can be achieved is clearly an emotional reaction to current-day stress, but it's really wishful thinking at every turn

I think there is more naivety presented in some of the writings than really exists in the worldviews of those involved in this loose affiliation. Maybe it's a flaw in style and presentation, but I wouldn't interpret it in the same way you are. Not wishful thinking.
