You severely underestimate the biological side of things regarding social interaction. Neurodivergent people are what we are not just bc "surroundings made us so"
Then I don't understand what you are arguing about. If you're neurodivergent, you would always require self awareness and masking, faked as op rightfully stated. You could never natural, no matter what circumstances were.
Changing is possible even if you're neurodivergent, but you'll always have some barriers that neurotypicals don't. To interact with them, you will generally need some degree of masking.
