I don't think having zero support needs is realistic. If you have for example sensory issues like being sensitive to bright light or having trouble eating certain food then this doesn't go away. And just living in a world made for neurotypical people will always be a bit distressing and cause social problems.

Yes, there is a bit of a contradiction in advocacy because on one hand we want to spread awareness about the natural diversity of how humans brains work and remove prejudices and celebrate that diversity but also we don't want to minimize that it is a disability and people do need help.
