From what I can decipher from his and other claims to support “universal” medical care, a “market failure” occurs when someone is not able to access immediately all of the medical care he or she “needs” immediately.

Now, if this is what he means by a “market failure,” then every market (including the distribution of government-produced goods) falls into that category. If I cannot afford a Rolls-Royce, is that due to “market failure”?

The very term "market" implies the presence of voluntary exchanges being transacted by individual parties to their mutual benefit...not the mandates of government.

Government involvement in medical care, and especially the advent of Medicare with its third-party payments for nearly all medical care hastened the invasion of the modern mess.
From an economic point of view, a scarce good is a scarce good, whether it is medical care or sirloin steak. The problem is that government has piled intervention on top of intervention, and driving up the costs and making care less available in the process. The “failure” of the present system is a government failure, period.

Excellent article, Rustee.

I really like this part:
