Addendum 2:
   Obviously we need doctors because they're our channel to extensive
   scientific research and medical lab tests like mris, xrays, eegs, pet
   scans.  Those things are all behind huge financial walls.
   But we also need doctors to integrate research a lot more effectively
   in both directions, to heal our communities before our minor aches, and
   to protect us from abuses by corporations, organised crime, and
   government.  In my area, if you want to get tested for rare and very
   dangerous pollutants, you have to find a third party study.  Doctors
   generally assume it's something that doesn't indicate a class action
   lawsuit.
