Because nudity without sexual desire is a perfect utopia. In the same way that motherly love divides instead of multiplies as every new kid is born, there is an incorrectness, a cruelty, in the natural order of things. Nudity is connected to sexuality. Why is it that human beings since the dawn of time have been hiding their genitals? When the woman grows up to have breasts, she must understand how that will plague her life: Her being wanted sexually, and her sexual wants.
In a utopia, human beings can be naked, and there is no taboo about it, no shame, as much as there is no shame in wearing clothes. We finally understand and appreciate the flesh clothing we wear. We don't have to hide to each other, we can truly experience a joie de vivre.
