Don't misinterpret my point: I think the government should absolutely pay for necessary medical treatment like this.
But, it's important not to confuse what are actually two different inquiries: what is the fair price for a Hep-C cure, and how do we make sure those who need get it. The first is a purely economic question, not a moral one. Otherwise you create a perverse incentive structure: people make lots of money creating things people don't need (a new iPhone model every year), while people make much less money creating things people do need (breakthrough cures).
