The coverage provided by the "free and open market" you refer to isn't affordable. And I'm not pretending that Obamacare fixed this problem, or that the solution looks at all like Obamacare. 

Paying up to 400 dollars a month and then still paying high costs when you actually go to the doctor is not "affordable". I lived in Belgium for a significant part of my life and I know what a more social health care system should look like. 

I believe that I would have much more time and money available to me - and many people in my community would - if paying for health insurance wasn't something I or them had to worry about.

Yes. I think that with the internet, roads, building and housing regulations, car regulations, and communications and financial infrastructure the ability for you to help others financially or with time has gone way up. 

People have much more free time to help each other in the socialist countries in Europe than here where you can barely get a two week holiday.
