I'm not sure how it's done in Mexico but this is a perfect example of an industry where Truth in Advertising and strong liability laws would be enough "regulation" or public involvement in care. Licensing and labelling doesn't need to be regulated by the state. Laws that say "You can't cut someone's healthy genitals off." would be reasonable.

My healthcare should be between me and my doctor. As long as everything is explained to me I should be able to take any experimental treatments I want. If he does something weird or unconventional that harms me - and the risk wasn't properly explained and waived beforehand - then my family or I could sue him for all he's worth.

As far as public health goes, all you need is an advisor or council of practitioners advising executive decision makers. (President, Governors, Mayors) Once they start asking for and getting money from gubmint then there will always be an incestuous relationship of control and advocacy. Also Pfizer was bribing everyone. That's a problem with giant influential state-subsidized corporations in general, and not pharmaceuticals specifically.
