It would be a fact that this empty universe was a lot better than a universe full of people who were in immense misery. And this would mean that there was an ethical need for the emptiness to continue rather than being replaced by a universe of infinite suffering. But there might also be another ethical need in the opposite direction—a need for this emptiness to be replaced with a good universe, one full of happiness and beauty. And Plato thought that the ethical requirement that a good universe exist was itself enough to create the universe.
I fully agree with this
