Medicine is insulated from the real world in many ways, and the more you examnine it, the more disturbing it becomes. The situation is so bad that often the most basic of Constitutional rights have been tossed aside in order to protect the financiall interests of certain institutional players. As far as I know, one country and one country alone has attempted to protect its citizens from a loss of medical freedoms by actually including it in their Bill of Rights. (Thanks to Dr. Thomas Levy for calling my attention to this fact. See his site Peak Energy.)
From the New Zealand Bill of Rights Act of 1990:
"You have the 'right not to be deprived of life.'"
The exact wording of the legistation reads as follows:
"No one shall be deprived of life except on such grounds as are established by law and are consistent with the principles of fundamental justice." 
These words and concepts are incredibly important and, as Dr. Levy points out, the "intentional withholding of a life-saving therapy" would violate this right (and a good deal of common sense and human decency).
Why can any of us not buy any of us purchase a therapy of our choosing in order to try to save our life? There are many well-documented examples of cancer pateints who are not allowed by the FDA to receive experimental anti-cancer drugs. Why does the FDA have the right to deny a patient who is in a life and death situation and is willing to pay cash the right to try to save their own life? Well, they shouldn't of course, but thousands upon thousands of men and women have died because of the FDA's unconstitutional exercise of its powers.
Here are just a couple of examples out of literally hundreds that have been squashed or delayed by at the federal level:
a) Provenge. William Falloon (President of the Life Extension Foundation) in his groundbreaking book Pharmocracy talked about many cancer drugs that had cured patients or extended life and het the FDA banned these drugs from going to market. One of the most glaring and egregious examples was the drug Provenge, which had several studies backing up its efficacy in the fight against prostate cancer, and yet the FDA said, "No, cancer patients. You cannot use your money to buy one of these drugs and potentially save or extend your life."
William Falloon conservatively estimates that over 80,000 life-years were lost due to the FDA's 8 year delay in approval for Provenge. And, in the meantime, the cost was driven up much higher.  Perhaps this the intent all along?
b) CBD Oil. Another excellent example is CBD oil. This is oil extracted from low THC cannabis plants and has powerful anti-inflammatory and anti-cancer properties. Again, why can an individual willing to pay cash not purchase CBD oil and attempt to save his life? It has virtually no THC in it - the psychotropic component of marijuana - and so there is no logical reason for the FDA to be regulating it in the first place. Fortunately, one can now purchase CBD oil in many states due to the legalization of medical marijuana. But it is still not a given in our country.
Who does all this protect? It certainly is not protecting cancer patients who have less than a year to live. The only answer to that question is that protect the large pharmaceutical corporations producing less effective and much more expensive solutions and forcing them upon the general public. Fortunately, the eyes of millions of people in our country have been opened up and maybe someday here in the U.S., we will also have a Bill of Rights that protects us from the fundamental right to preserve your own life.
