as i was saying to judge motz that, is a virtually universal feature of human existence. everyone is going to seek health care. nobody can know precisely when. providers can't opt out of providing it. if you show up destitute, there is still a duty to treat. and it's sporadic and unknowable. this makes this market different than some of the fancyful things. >> you have gone beyond the initial step, first, before we get to the participating health care saying i guess you don't need at this point, basically making a choice as to whether you're going to get health insurance and the characterization there is that is an inactivity to require someone to do something they don't have to do, that is to get insurance is a characterization. the issue there as opposed to the choice for whether to participate in the system. >> i guess maybe the best way of putting our arguments is we're not focusing on inactivity or activity. those words they eventually can break down semantically. we're asking what the commerce clause is about. we're asking does the conduct that is being regulated ha
