To address catastropic insurance, I have no problem with the free market handling the issue of what is covered and what is not but the fact is unless everyone has coverage or can afford all their bills, everyone else ends up footing the bill when someone defaults. Either way, the public is subsidizing other peoples health care. Right now it is other health care users that pay for it (through higher medical costs). Requiring everyone to have such coverage would expand the group of subsidizers to the whole population.
