I would say that we don't have the social experience of dealing with something truly finite. We've always lived in a world of money and wealth being somewhat infinite. At some point, bitcoin becomes zero sum, we all trade and fight and scrap for the same amount of bitcoin. From birth, any bitcoin you earn is taking it from someone else. Yes the pie of goods and services can grow larger, and bitcoin becomes more divisible. But as a social construct, we havent seen how people would act in this framework.
