For a doctor, I don't think I care very much if they have completed bachelors or not (in the US they are more or less required to for acceptance to medical school, but I don't see what good this does me as a patient).
It doesn't do shit for you as a patient. A certainly not any more than trading that 4 yr lib arts degree for 4 more years of medical training. Universities as gatekeepers to actual jobs without is something that definitely needs to be addressed but you'll probably never see them bring this up. Imagine how bad for business it would be if all Universities offered was a chance to learn.
