That's a pretty problematic attitude toward disability. Firstly, in that you would equate someone choosing to remain how they are with someone who would support homeopathy to cure a fatal disease, and second that you dismiss the lived experience of a great many disabled people who certainly do consider their unique circumstances as, if not positive, at least integral to who they are and the life they have lived and not something to be 'cured'. They would no more change it than I would my eye colour. The deaf community, for example, are quite militant on the subject.
The other problem with 'cures' in speculative fiction is that they are not available in reality. They reduce the experience of lifelong disability to that of having a passing illness, and make disabled people even more invisible. In TV land, if you break your back, odds are you will miraculously walk again by season's end. Imagine what that is like to someone to whom their wheelchair is with them for life.
