If I'm trying to sound alarmist, it's because I am trying to sound alarmist.
The Supreme Court, based on oral arguments, appears to be dead set on overturning the Patient Protection and Affordable Care Act, on the basis that Congress cannot force people to buy something, in this case, health insurance, even if the lack of a mandate to purchase health insurance causes costs for everyone else who uses the health care system in this country to skyrocket without abandon.
If the Supreme Court goes along with striking down ObamaCare, we could very well be on a fast track to another Civil War over the concept of states' rights versus the concept of strong central government. If the individual mandate that is the core of ObamaCare is struck down, the Supreme Court is setting a destructive precedent that would quite possibly break the Union. Do other mandates by the federal government, such as paying federal taxes, become unconstitutional? Not right away, obviously, because the Supreme Court is only considering the constitutionality of ObamaCare. But, as anyone who has even the slightest bit of knowledge of how the Supreme Court works knows, if ObamaCare is overturned by the Supreme Court, that precedent could be used to overturn other mandates by the federal government on the states and the people.
Again, if I come across as alarmist, it's because I'm trying to be alarmist.
