Fwiw I think this is basically correct, though I would phrase the critique as “the hypothetical is confused” rather than “the argument is wrong.” My sense is that arguments for the malignity of uncomputable priors just really depend on the structure of the hypothetical: how is it that you actually have access to this uncomputable prior, if it’s an approximation what sort of approximation is it, and to what extent will others care about influencing your decisions in situations where you’re using it?
