Using the same idea, are you personally for legalizing all drugs as well or not requiring doctors to be licensed? Because I think there are lots of things forbidden/regulated across the world, mostly because people do not to make (or are not able to make due to lack of information) the best decisions for them, and then society suffers as a whole.
Me personally, if I have to choose between food 10% cheaper that will give 1 in 1000 people a cancer, or eating something more local/boring I prefer the latter, even if I would never buy it myself.
I already stated in this thread that I'm in favor of smart regulation, not zero regulation. For example, instead of government licensing of doctors, I would be interested in a more elegant solution like requiring all doctors to carry malpractice insurance and publish information about the insurance rate they're currently paying. If graduating from a particular medical school is truly associated with reduced malpractice rates, that should be reflected in lower insurance rates for those doctors. Insurers would design their own exams which would probably be better than government licensing exams since insurers have skin in the game.
The problem is the "root of trust". Someone has to decide if it was "malpractice" or not. The doctor (and the insurer) have the interest to say "it was the best service we could provide", and even if you involve a lawsuit/judge/etc., they will have no clue who is correct. And if you have a "root of trust", they can directly test/manage the doctors (the current system).
Returning to the topic to which I responded: I prefer some organization responsible to make and check a set of rules about food, rather than each person to have to do their own research (and the first does not exclude anyhow the second). I find that smart in the sense that it will reuse knowledge of some people and will not require a lot of people learning a lot of things. I have the impression that I do care about food quality more than the average, so I am not at all worried about too strict requirements.
