I see a public body as more able to strive towards key goals around fairness and access such that these really tough decisions.... Many of them will be challenging decisions. If you are a patient without any treatment options, you are going to consider that medicine essential, but the evidence base at that point in time and the price at that point in time may make coverage prohibitive.
I think if we are really thinking in terms of those public health care kinds of values, a public body is better suited to take on that tough decision-making process than a private one.
