Dunbars Number refers to the idea that that humans are evolved to live in groups of 150 or less.

Above that, we require abstractions like money to cooperate with strangers by reducing the need for trust.

Bitcoin does that better than any other money in human history.

I love the id a of living in a village with 149 other trusted individuals, but I also really enjoy internet access, air travel and the majority of babies living to maturity. So I’m gunna go with the best money I can access to facilitate a better life.
