I don't see the need for any rules. Not made up by "government". I don't even see a need for doctors to be licensed.
When some quack offers your son some ill-conceived, untested protocol that happens to be fatal, you might be able to sue the quack if you can find them, and if they have any assessts, but it doesn't bring your son back. Licensing ensures a minimal standard of appropriate care. I have no desire to return to the era where the surgeons were the barbers.
If we have government "authorizing" medical practitioners, that means someone in the government is deciding what medical practices are effective or "in the public interest". That's not the government's training or expertise.
"The government" has no training or expertise in anything. Individual government employees and consultants have training and expertise. Do you think the government fails to hire/consult medical organizations like the AMA as well as individual doctors?
It's not a lot different from a "state-sanctioned religion". You have some special folks in government with the power to determine what we should accept or believe or choose in regard to our own fundamental personal right to life.
Nonesense and stupidity. There is no law forbidding you from indulging in any sort of quackery for your own benefit. Licensing just recognizes that the needles they are sticking in you don't actually do anything medically, that the shaken water doesn't really cure anything, that the coffee enemas don't really draw out cancer cells. It does not stop you from throwing your money away, although it prevents quacks from billing insurance companies, and throwing other people's money away.
If the government didn't try to do this, doctors wouldn't be regimented the same way. But even old tribal witch doctors had norms, shaman norms, and so would contemporary "experts". It would be a matter of each doctor deciding whether no not to have a reputation for being effective or competent, looking at other doctors who had tried a brand of medicine and what the results were.
Doctors are still human. They are still vunerable to confirmation bias, the Dunning Kruger effect, overlooking the effects of the regression to the mean, pareidolia, etc. So, your recommendation means that every time I have to get a new doctor, I have to grill them on their methodology for selection of treatments, ask to see the peer-reviewed studies, etc. The indsurance companies will need to make the same determinations individually. While you should never put blind trust in a doctor, there is no need to create a deeper chasm of suspicion between doctor and patient. Except for those patients who'll just trust the doctor, anyhow, so if they get sick and die from inefective medicine, it's their own fault for not taking a couple of hours researching every suggestion their doctor makes.
There would be some doctors out there trying different things and reporting results in a medical journal somewhere. I bet doctors would also be looking at what insurance companies would pay for, and insurance companies would be looking at medical journals where reports of treaments and results were being reported, maybe paying some doctors to do some surveys/studies. . . . and then maybe writing some rules themselves. . . .
That's what we have today. Doctors, often through their medical societies, do write the rules themselves, and are the primary enforcers of them.
Maybe people would stop patronizing ineffective or fraudulent organizations. . . .
That doesn't happen today. Why would that change?
Point is, if government didn't weigh in on medical practices, there would be some other organized effort at standardizing practices. Maybe you want your politicians doing this kind of business. I don't.
I'd rather the politiciaqns get the insight of the doctors, which they do, combining medical expertise with legal expertise. I'm just crazy that was.
Food or supplements would probably not be something medical schools or insurance companies would aggressively study, but there would be a market for information in this area as well. As long as folks have free speech and free choice, some folks would be chattering about subjects like this. If you had a problem, you could probably find something about your particular problem. Might be a lot of different ideas going around. Maybe some different products available. If you wanted you could spend some time trying to figure out what makes sense, maybe try some different things. Some folks might be sorta "expert" about all this. Maybe write some books for others to read. Might be interesting.
Sounds like what we already have.
Might just give some folks a headache doing all that reading. Maybe some folks would rather have politicians deciding what we should eat, or what kinds of supplements are effective.
Personally, I'm becoming quite fond of the idea of some quack selling you medicine made from rotting leaves, urine, and snake-oil, telling you it's so cheap and effective the big pharmaceutical companies can't make a profit from creating it, so they are burying it, and that's why you can't find any independent information; telling about the one person who recovered from their cancer and not the nineteen who died; having you drink it while you are at the height of a cold, and then watching you miraculously recover from it in 2-3 days. It's the world you would create for everyone, and it's what you deserve on some levels.
I think people who are just lazy or stupid should not be trusted with the power to make decisions for me. If we did that I bet some supplement and food providers would try to influence legislation and set up some kind of favorable racket for their stuff.
They have.
