I recall our founding fathers had argued this, but it was never resolved and left unresolved.

"Unless we put medical freedom into the Constitution, the time will come when medicine will organize into an underground dictatorship....To restrict the art of healing to one class of men and deny equal privileges to others will constitute the Bastille of medical science. All such laws are un-American and despotic and have no place in a republic....The Constitution of this republic should make special privilege for medical freedom as well as religious freedom." -- Dr. Benjamin Rush, a signatory of the Declaration of Independence

"“Conferring exclusive privileges upon bodies of physicians, and forbidding men of equal talents and knowledge, under severe penalties from practicing medicine within certain districts of cities and countries. "Such institutions, however sanctioned by ancient charters and names, are the Bastilles (Propaganda masquerading as science) of our science.” -- Dr. Benjamin Rush, a signatory of the Declaration of Independence

“The accumulation of all powers, legislative, executive, and judiciary, in the same hands, whether of one, a few, or many, and whether hereditary, selfappointed, or elective, may justly be pronounced the very definition of tyranny.” ― James Madison, Federalist Papers
