Interestingly, while from the beginning the word utopia was used to refer to a desirable (perfect) society, etymologically it simply means a place that does not exist.
In contrast to dystopia, which is clearly a bad place.

This isn't true, I think? Assuming that it derives from the Greek τόπος (location), it literally means "good place" (εὖ-τόπος). The no-such-place translation in Greek would probably be ἄτοπος, but that's an existing word and uses one of the other meanings of τόπος (it means uncommon or absurd).
