Why can't we have both? There's no regulation on rating doctors at the present and it seems to me like the fact that there aren't a dearth of patient/consumer ratings of doctors already precludes your assertion that if we stop requiring certification that many will suddenly spring up.
There's also the problem that medical care is an inherently non-free market. If I'm bleeding to death, I don't have time to search the BBB's ratings on a hospital and decide which emergency room I'd prefer. The same is true for pricing: If I'm dying my demand for service is going to be irrespective of it's price.
Regulation is a critical component in the medical industry, in my opinion.
