So what might Gender Disintegration fix? It might fix salary differences between the Sexes since Sexual Identity would be mired in a Gray area. As described above, Shaming would be somewhat more difficult as Society could adopt the Pee Wee Herman Defense when he flew over his bicycle handlebars in front of a group of impressionable young teens and said, "I Meant to do that". Life is no longer about competing with the same sex and possibly always being last or near least. Every adventure would have different blending of people and inevitably people who are not good in one thing may shine in something else more often then if they are always competing within the same Sex.
As for the strength argument as being something that cannot be ignored, Society is becoming infiltrated with robotics and the ability to control powerful robotics and automations from a distance, thereby diminishing the need for more physical strength.
My reservations revolve around the idea that everyone starts the same and then turns into something different. I personally like the idea of two sexes, identified at birth, and then each blossoms into whatever they want to be.
