Oddly enough, when I lived in more rural/suburban settings, I never really encountered anything I'd consider communal or primal/"paleolithic" but when I moved to a bigger city, I found many more ways to address those desires.
Even if it's just having a corner bar where neighbors stop in for a meal or a beer in the evenings or getting together with nearby friends on various nights for board games or cookouts, I see a lot more community and shared activities. Much of it is only enabled by the proximity of urban life where the need to drive over to meet up is minimal or nonexistent. When I lived in the "boonies", any gathering had to be a lot more scheduled since you had to account for driving.
