A person without legs does not stop being disabled because they have no need or desire to walk. The fact remains that should they need or desire to walk in the future the hinderance will still very much exist.
A similar example could be made of someone with gluten intolerance. If they do not eat foods that contain gluten they are still gluten intolerant. They are however still disabled by needing to stay in that situation.
