A political order may be adopted, imposed, etc, but "society" is something humans, as social animals, develop spontaneously. Proper governance of society follows understanding of human nature and the human condition as well as the contingencies of Man's existence. It is no trivial matter, of course, and utopian ideologies have a particularly bad record with philosophical anthropology. Furthermore, Man is a moral animal. His moral perfection is not a given and must be worked out during his lifetime through effort. Utopians, sadly, often like to blame "the system". Mind you, "systems" are always the product of morally imperfect and ignorant men for morally imperfect and ignorant men. Utopians tend to think they can somehow circumvent all of that. Add to all of this the consequentialist tendencies in the political discourse.
