> The division happened when transitioning from hunter gatherers (which didn't need possessions, just hard work)
I am sure hunter gatherer societies were also very territorial. If the area you are hunting or gathering does doesn’t have much animals or plants, all the hard work won’t get you nearly as much food as someone who has a lot of plants and animals on their land.
And if you don’t think early humans were territorial just take a look at chimpanzees or even lions. Being tribal and territorial goes back a long ways.
