In the new order a person would not notice that a woman was more beautiful than another woman. Because that basically means that genetics would still be creating people with not so pretty traits (ugly). Either everyone would be strangely and boringly equally good looking, or perfect minds would not notice and care about the way another person looked.
Noticing that one person is pretty and another ugly is not a kind, or perfect thing to do. Having people always tell your sibling how beautiful they were and then tell you how nice you can weave that basket, would certainly create situations that were not "perfect".
Even before waking up I had thought this through and concluded that not all girls would have perfect breasts, some woman are pear shaped, some woman have larger legs and really tops, some noses are long and some noses have humps on the top. Some men are skinny and super tightly packed with very lean muscle while others are heavier and full bodied despite not being overweight. So if paradise were real then physical traits would not matter anymore.
