The moral of the story here is why empiricism and material analysis are so important. Liberals are adherents of Idealism, which holds that existence is inseparable from human perception and that reality stems from the mind. This leads them to think that they can just will reality into existence through sheer force of will. They reject the primacy of the physical world and brush away question about pesky details such as industrial capacity, logistics, and so on. This is an excellent demonstration of Dialectical Materialism being a superior framework for understanding the world.
