The only real lesson of the ObamaCare defense is that if you define the macro broadly enough, you are entitled to completely control every aspect of the micro. Everyone can be compelled to buy health insurance because health care is no longer a service bought from a doctor, it is a national market which everyone by definition participates in. The market is then divided between good consumers who buy health insurance and the parasites who don't. Alternative possibilities such as people who pay as you go, choose alternative health care or reject medicine entirely for religious or political reasons don't figure into a macro equation which sees people in the macro, not as individuals.
