I think it's arbitrary. Utility functions are an abstraction for
describing agents; if two agents would make the same decision in all
situations, then it makes sense to say that they have the same utility
function. Rescaling a utility function has no effect on the decisions
which would be made by an agent which implements that utility function,
so it's really the same utility function.
