This matches my intuition on the subject. It also matches my intuition of the problem of Nozick's Utility Monster. Yes, total utility will be maximized if we let the monster eat everyone, but it introduces a large disparity: huge utility for the monster, huge disutility for everyone else.

The question is, is this a "valid value" or a problem? The only way I can see to answer this is to ask if I would self-modify to not caring about fairness, and I don't know the answer.
