This still doesn’t seem to address why one should be risk-averse and prioritize an impoverished survival in as many branches as possible. (Not that I think it does even that, given your examples; by always taking the risky opportunities with a certain probability, wouldn’t this drive your total quantum measure down rapidly? You seem to have some sort of min-max principle in mind.)
Nor does it deal with the response to the standard ensemble criticism of expected utility: EU-maximization is entirely consistent with non-greedy-EU-maximization strategies (eg the Kelly criterion) as the total-EU-maximizing strategy if the problem, fully modeled, includes considerations like survival or gambler’s ruin (eg in the Kelly coinflip game, the greedy strategy of betting everything each round is one of the worst possible things to do, but EU-maximizing over the entire game does in fact deliver optimal results); however, these do not apply at the quantum level, they only exist at the macro level, and it’s unclear why MWI should make any difference.

Do you think making decisions with the aid of quantum generated bits actually does increase the diversification of worlds?
