Now, you should be free to (and not prohibited from) obtain health care services through free and voluntary exchanges, but you should not be able to demand health care services from someone else or force someone to provide them for you. Anyone should also be free to provide health care services (free of charge or in exchange for something).
Point no. 1. Healthcare is not a business. If you get into an accident and break an arm you cannot "go shopping" for the cheapest doctor that will fix your arm for the least $$. If you cannot shop, it is not a business. If it is not a business then it needs to be regulated by the government, just like the government regulates criminals, maintain highways and electricity providers. Right now insurance companies are free to do just about anything, including denying claims which gets people into bankruptcy.
Point no. 2. Healthcare is not optional. To put a very simple example, if your neighbor does not get vaccinated because he is a nut who doesn't "believe" in vaccines, your kid may contract swine flu. In other words, you may think you are a separate individual with responsibility for your own health but the disease does not care what you think, it only cares about how you act. Other noninfectious diseases have some degree of transmission as well. Case in point, obesity. If you don't take care to educate and promote good habits for everyone, but only for those lucky to have insurance, the effectiveness of treatment will be diminished, and by a lot.
Point no. 3. It just makes sense. Like stinkbug said: a sick society will ultimately fail. OK? With the number of uninsured rising over time when will you draw the line? When half of the country cannot get a colonoscopy or breast cancer? Oh don't worry, they make minimum wage so they don't count...
