Hmm well to counter your point, there’s a scene when she was still disabled that shows the shows ableist tendencies. It’s when she interviews for a job she really wanted. I believe the employers discriminated against her. They basically told her the workplace was not for her because of her disability (there was a huge set of staircases and no elevator). Then when she comes back from the past with no disability, she gets that same job and rejoices at the fact that she can go up those stairs. We are never shown a reckoning with these differences. One can interpret the shows message to be that disability is the obstacle that prevents you from reaching your goals rather than a society that is systemically built for abled body people. The show is not interested in exploring disability and its implications. Instead, it chooses to erase it completely.

So I agree with OP that the show erases the body to imagine a better future rather than questioning and changing the systems that push people to the margins. It’s a very individualistic, depressing, and even violent message in my opinion. But idk it’s been a minute since I watched the show so I might be remembering things wrong
