The issue of forcing people to be cured / treated / engineered in order to overcome disability is a separate one. There are some forms of disability which most people with that disability would want 'fixed' -- anything from myopia to lost limbs. There are others where the perceived benefits may outweigh the disability. (A friend has chosen not to be medicated for her depression, because the meds -- or all the ones she's tried over the last 20 years or so -- destroy her creativity, and she's an artist.)
[I kind of want to do a poll now -- 'what disability do you have that you would 'fix' if you could undergo brief painless treatment? What wouldn't you fix?']

If treatment is forced upon the person regardless of their wishes, that's definitely saying 'you're not okay' -- because it is erasing the individual's wishes, forcing them to conform. If treatment is made available (and here's yet another can of worms regarding cost and accessibility), I don't see that this reflects badly ('not okay') on the individual.
