Revoke the concept of a medical licence! Maybe charge $10k a year for one (so doctors are still registered, theres just no other barrier) and boom, now you can prescribe whatever you need. If that medical degree and residence program is really worth it then the market will price it in. Healthcare costs will fall drastically. Its the cartel of Doctors that keeps costs high, every medical decision gets made downstream of doctors. No doubt quality will fall in the cheap end, but the care per dollar will go way up.
