I disagree. I think it's entirely likely things started along the lines of "We gather here every year this season to share in the peak hunt festival. Let's make a mark upon this place" and over a few centuries that grew motivating enough for people to incrementally build more elaborate megalithic structures. This is just my view, and I'm certainly no anthropologist. But I would point out this narrative exactly matches what we see at Gobekli Teki: layers of megalith construction, each covering and supplanting the previous.
