It's not a challenge to write a fiction book that paints a picture of a world that is better than ours. The problem isn't so much that the fiction is bad, it's that it's just entirely insufficient to be persuasive about real issues. It's like watching Star Trek and then deciding we should all live in a socialist utopia. Star Trek is very compelling, but there's a limit to how much it instructs us about the real world. Rand operates closer to a Peterson style self-help book than a real political philosophy.
