Health insurers -- once private companies -- are now organs of the federal government. Every citizen is a ward of the state, which can now compel you to have insurance, punish you if you don't; determine if your insurance is acceptable, punish you if it isn't. Thousands of new federal bureaucrats will soon spill from the D.C. Beltway and flood the country, scrutinizing our finances to verify compliance with this new law.
A government that grants itself this kind of power over us can conceivably do anything to us. For our own good, of course. Such a country is in no meaningful sense "free."
And this is only the beginning.
