I don't think we disagree that having a healthy population is good for a functional society. This requires preventive and maintenance healthcare "needs" --but would not include "wants" like cosmetic and elective options. If your eyelid droops but you can see well, I don't think that's necessary. If your hair is falling out and you want implants, if your mammaries are small or drooping I don't think elective options are necessary. We need to keep people healthy, we do not need to keep them attractive. So for Example I would not include "ED" --that's independent of health.
