Apples and oranges
The thing I find highly ironic is that if the Democrats had had a pair amongst them and pushed for a single payer, government run health system the plan WOULD pass Constitutional muster. Essentially we'd be talking Medicare/Medicaid writ large. The US government would collect more income taxes (allowed by the 16th amendment) and wasted the money to cover medical expenses. Instead they turned chicken and passed a bill with the "individual mandate" that isn't going to work.
There's a fundamental principle at work here that apparently some people are too obtuse to grasp. If the US government wants to operate a plan and tax the public in order to do so, it's Constitutionally allowed. Foolish, wasteful and ultimately doomed to failure but Constitutional.
On the other hand if the US government says "you must buy this product because we say so" then we have a problem here. After all, if the US government by act of Congress can make you buy health insurance then what CAN'T if make you buy? If the commerce clause has no limits to the authority granted Congress then a number of our rights specified in the 5th, 7th and 9th amendments become meaningless.
We haven't touched the fact that health insurance policies are NOT in fact issued across state lines so the idea that Congress can regulate it as interstate commerce is a rather shaky proposition to begin with. One that the courts haven't had a chance to comment on at this time.
How many people will die, "saving" taxpayer money are all nice emotional arguments that really miss the point. I'm being kind here because some political figures have no excuse for not understanding the problems with the individual mandate program. There are lots of things government "could" do that would save a lot more lives like banning automobiles and motorcycles altogether and making everyone use some sort of public transit. Or outlaw any activity that could result in bodily harm such as skydiving or bungee jumping. But at what cost to individual freedom? Freedom to only make nice, safe choices isn't freedom at all. Cattle are safe. Cattle are fed regularly, get free health care and, for a cow, a nice place to stay. Cattle are NOT, however free.
If you want to be cattle, fine by me. I'd plan on staying free.
