However, surely there are possible agents who are major fans of Bayesian statistics who don’t have the time or motive to share their knowledge with other agents. Indeed, they may actively spread disinformation to other agents in order to manipulate them. Those folk are not bound to agree with other agents when they meet them.
I assume this just means that their primary epistemic goal is such, not that this is their utility function.
That’s why I used the word “involves”.

Won’t the utility function eventually update to match?
