CHIEF JUSTICE JOHN ROBERTS
: So, can the government require you to buy a cell phone because that would facilitate responding when you need emergency services? You can just dial 911 no matter where you are?
SOLICITOR GENERAL VERRILLI
: No, Mr. Chief Justice. I think that's different. It's -- we -- I don't think we think of that as a market. This is a market. This is market regulation. And, in addition, you have a situation in this market not only where people enter involuntarily as to when they enter and won't be able to control what they need when they enter, but when they --
CHIEF JUSTICE ROBERTS
: It seems to me that's the same as in my hypothetical. You don't know when you're going to need police assistance. You can't predict the extent to emergency response that you'll need, but when you do -- and the government provides it. I thought that was an important part of your argument, that when you need health care, the government will make sure you get it. Well, when you need police assistance or fire assistance or ambulance assistance, the government is going to get it.
