You can define a utility function on gambles that is not the expected value of a utility function on amounts of money, but then that function is not expected utility, and you’re outside of normal models of risk aversion, and you’re violating rationality axioms like the one Eliezer gave in the OP.
Having a utility function determined by anything other than amounts of money is irrational? WTF?
