Disagree. A grown-up wants treatment for a really existing pain, after being fully informed of the potential consequences. Her body, her choice, and maybe (although she stated never wanting children) her responsibility.
Many people, after all, completely change their mind on having kids later in life.
I agree with you about the disclaimer, but play out the situation-
Within a few years you will see a sharp rise in prescription of fertility-destroying drugs. At some critical mass, we will see lawsuits saying the drug companies find a drug that does X, but destroys the fertility of women and then just stops doing more research. This is similar to the development of the pill. It had nasty side effects for some, but not enough to economically justify more development until the law and massive public pressure came in.
But in this case there was no child. She’s an adult woman in pain and her doctor failed in his duty to help mitigate that pain. I wonder if she could sue. But given this 1950s leave-it-to-beaver right wing Supreme Court we have she might not have much recourse. Which is a shame.
