Hmm... Atlas Shrugged does have (ostensible) paragons. Rand's idea of Romanticism as portraying "the world as it should be" seems to match up: "What Romantic art offers is not moral rules, not an explicit didactic message, but the image of a moral person—i.e., the concretized abstraction of a moral ideal." (source) Rand's antagonists do tend to be all flaws and no virtues though.

Everyone in that book acts nearly completely diametrically opposed to their interests were they in the real world.
