Can you invent a utopia? A utopia is an incoherent concept about a society that contains too many internal contradictions or impracticalities to ever exist. Thus, it cannot be invented any more than a perpetual motion machine can be.

If you do consider utopias inventable, what's the difference between "inventing a new utopia" and "having a new preference"? You want X; you dream of a world where you get X, inventing Utopia X.
