I still don't clearly understand what point you're trying to make. Do I think the entire states of Texas, Oklahoma, Arkansas, and Louisiana contain no people who understand SCOTUS precedent and legal history? I somehow doubt it. Each of those states have legal scholars, attorneys, and public policy grads, among others. I don't know how they could have missed one of the more important doctines of case law in the last 100 years. The new emphasis on states exerting 10th amendment freedoms clearly carves out areas that ARE NOT interstate commerce. For instance, (I think it was...) Montana has tried to argue that weapons made and kept in the state should not be covered by Federal Law. I'm not sure even that idea is going work, but...
Surely you can see why healthcare is different than guns created and kept in Montana. Healthcare is a much less tangible object, and one that would be nearly impossible to confine to a state. Companies operate in multiple states, people (like me) work in one state and live in another. People travel and get sick. And then there's all the Federal spending in Medicare, Medicaid, EMTALA, HIPPA, VA, and who knows whatever other programs, laws, and systems. And then there are the federal tax laws and breaks for consumer, provider, and employer. Like it or not, I don't believe it is a winning argument to claim healthcare is not covered under interstate commerce.
Now you may disagree with that line or cases, lots of people do, but it doesn't make them invalid. None of this is new, indeed lately it's been moving more towards state's rights...
I have a spare Con Law book here. If you pay for shipping and promise to send it back I'll let you borrow it.
