I'd never use a doctor, they're not tools.
But I'd absolutely seek the advice of doctors who never had formal education. In fact, based on hard evidence and history, I'd be more interested in what some outside-the-box professionals have to say about a given condition than to have someone recite a textbook paragraph to me that I could read for myself for free at the library.
I can't think of one profession or activity that requires a college-level education in reality, though there are plenty that legally you need licenses, etc. for.
As you hopefully would not, therefore your argument has a flaw in it, you might like to enumerate the list of professions or activities you believe do not require college level education.
