Arguably space ships look cool, but are mechanically wrong. The millennium falcon cannot exist due to its structure and equipment, yet is one of the most recognizable and liked space vehicles in all of fictions history. And for your fallacies, the point is you are nitpicking at a game of pure fantasy and fiction. Trying to make sense and say something shouldn't work is like going to a Lord of the Rings convention and saying the one ring shouldn't exist due to the impossibility of its construction and abilities.
