Smalltalk dispenses with text files; the language and the environment are inseparable. This allows for some of the really interesting features of the language, as it's always runtime, and you're working on live objects. Pharo is a nice version to try.

People don't listen to sad songs because it makes them sad; people enjoy sad songs. Tragic plays don't make you feel as if the tragedy had befallen you. And whether a war game is fun has nothing to do with whether war is fun.
Words are placeholders for concepts generally. The difference between using "fun" with Six Days in Fallujah and "fun" with Pac-Man is not a matter of the experience, but expedience.
You need a treatment or you'll die. How much are you willing to pay to stay alive? I'd pay everything that I have, because it does me no good when I'm dead. This doesn't depend on how much I have. In fact, I'd be willing to pay money I don't even have yet. This is why so many people go into debt to stay alive in the USA.
Assuming that there's only one person able to save my life, sure. Of course, that's not much of a market.
That one person is going to make a lot of money... so much that other people are going to want to be able to do what he does. Once there are a suitable number of people willing to save my life, I have choices, and the price will drop. We won't stay alive without food, either... and most of us would have difficulty doing so without housing. Markets are about supply and demand.
This glosses over a lot of important details, but so does the point being addressed. Possibly a good argument can be made that markets don't regulate health care well... but this isn't it. This argument doesn't address the most obvious free market predictions.
By the way, if there really is only one person who has the cure for your disease... be thankful he's there, and that you do have the choice to give him everything you have in return for saving you. You can still decide not to.
