Well, not exactly; I'm saying Solomonoff induction has implications for what degree of reality (weight, subjective probability, magnitude, measure, etc.) we should assign certain worlds (interpretations, patterns, universes, possibilities, etc.).

Utility is a different matter. You are perfectly free to have a utility function that assigns Ackermann(4,4) units of disutility to each penguin that exists in a particular universe, whereupon the absence of penguins will presumably outweigh all other desiderata. I might feel this utility function is unreasonable, but I can't claim it to be inconsistent.
