To be fair even this extract concedes that the medical benefits are barely significant. In general the convention is that you do not encourage a procedure if it does not have significant benefits, especially if it’s irreversible, especially on a subject who cannot consent to it. This one kind of gets the 3 strikes in term of medical ethics.

That being said it is very low-risk and generally done cleanly so i agree with you that it’s not the humanitarian thing that online circles want to make of it. It’s just one of those medical rituals.
