What I really meant is—the things in the tech report are fine as far as they go, but the Anthropic decision paper is where the real results are.
I agree with you that the isomorphism only holds if your reference class is suitable (and for selfish agents, you need to mess around with precommitments). The tech report does make some simplifying assumptions (as it’s point was not to find the full condition for rigorous isomorphism results, but to illustrate that anthropic probabilities are not enough on their own).
