I agree on most part with you, but it is not what that model is proposing. That model is mainly saying that it is society which is fault in disabilities, which is not true. Society's fault is in lack of tolerance and in very able-male-centric "standart" of building everything. It has something to do with capitalistic model as well, because disabled people are minorities, so there no reason to spend time and money to design and rebuild things for disabled people. That's why government need to intervene and that's why in more "social oriented government" countries, like in Europe, disabled people have much more quality of life, as it is demanded by government from everyone. Obviously all this should be done automatically, but majority of people are measuring others by themselves - so they may not even know that someone on wheelchair can need something more. Have you read "Invisible Women" by Carez?

Some people think the profession of psychiatry should be eliminated, which is ableist, because many people would suffer without psychiatry or access to medical treatment in general.

I saw that in USA and Russia mainly. Conservatives in USA and Russia are propagating that psychiatry and (especially) psychology does not exist at all and it is like Astrology, just a way to get money from stupid people. They think it has no scientific background and they do not believe those can help anyone at all (and religious conservatives can even say that psychiatry is creating of a devil to confuse people, as god can cure any diseas of a soul and any anxiety).
