Social orders function on the back of unfakeably costly signals. Proof of Work social orders encourage people to compete to burn more resources, Proof of Stake social orders encourage people to invest more into the common pool. PoS requires reliable reputation tracking and capital formation. They aren’t mutually exclusive, as both kinds of orders are operating all the time. People heavily invested in one will tend to view those heavily invested in the other as defectors. There is a market for narratives that help villainize the other strategy.
