Pfister and Kantargian et al do not understand that the value of an oncology drug to an individual patient cannot be objectively measured because such value is subjective. They also do not understand that the price (the money price) of a good in a free market is an objective measure of market exchange value. And, finally, they do not understand that the "just" price concept was refuted by economists several hundred years ago.
In the words of the illustrious Mr. T, I pity these fools.
