I've seen this type of argument by a few people who are against state medical care (not saying you're one of those in particular).
The product or service that extends your life is essentially not critical to survival or even just your status quo health-wise. From an economic perspective, this is a price elastic situation so charge as you like (i.e. basically according to supply/demand).
The situation that is actually the problem (and way more common, of course) is that if I'm in a life threatening situation I don't have the option to chose a particular product or service, that's price inelastic and not beholden to supply/demand. So you're comparing apples to oranges from an economic viewpoint, especially when we're talking about something as critical as healthcare.
For what it's worth, there are some UK parties, where if they got into power I suspect they would nationalise such a product/service for the betterment of everybody.
