An egoist is generally someone who cares only about their own self-interest; that should be distinct from someone who has a utility function over experiences, not over outcomes.
But a rational agent with a utility function only over experiences would commit quantum suicide if we also assume there’s minimal risk of the suicide attempt failing/ the lottery not really being random, etc.
In short, it’s an argument that works in the LCPW but not in the world we actually live in, so the absence of suiciding rationalists doesn’t imply MWI is a belief-in-belief.
