Ensuring a baseline ability of doctors doesn't ensure a baseline level of care. It can actually decrease the number of doctors and make it harder for poor people to get care. If you required all car mechanics to go to school for a decade and intern for four years, you'd get some great mechanics. Unfortunately, you'd end up with higher repair costs and more broken cars.

So yes, I'd certainly like to decrease the influence of the medical guild. While the average doctor would be less qualified, the average outcome would most likely be better.
