You're speaking of Bayesian agents as a general term to refer to anyone who happens to use Bayesian statistics for a specific purpose - and in that context, I agree with you. In that context, your statements are correct, by definition.

I am speaking of Bayesian agents using the idealized, Hollywood concept of agent. Maybe I should have been more specific and referred to super-agents, equivalent to super-spies.

I claim that someone who has lived and breathed the Bayes way will be significantly different than someone who has applied it, even very consistently, within a limited domain. For example, I can imagine a Bayesian super-agent working for big tobacco, but I see the probability of that event actually coming to pass as too small to be worth considering.
