Another problem is that you can only use VNM when talking about complete world states.
You can talk about probability distributions over world-states as well. When I say “tasty sandwich day minus normal day” I mean to refer to the expected marginal utility of the sandwich, including the possibilities with wizards and stuff. This simplifies things a bit, but goes to hell as soon as you include probability updating, or actually have to find that value.
