mandates that you purchase a private company's product for the sole reason of being alive.
If you ask the simple question of "what is to stop the Government from mandating that you purchase other things just for being alive?" you might get told the fallacy of "it's like auto insurance", when it really isn't; to avoid paying auto insurance you simply have to not own a car. How do you get out of the obligation to buy a private company's health insurance policy? By being dead. Most likely, though, you won't even get THAT flimsy auto insurance fallacy of an answer. Instead you'll get flamed and accused of spouting right wing arguments or whatever.
All you're going to get with that is more and more Americans asking, "What else will the Government order me to purchase from a private corporation, just because I happen to be alive"?
This question is legitimate. It will not die. It is not just being asked by right wingers. You cannot hide from it.
When middle class earners start finding that they're going to have to stop paying a car note to buy a private corporation's health insurance policy or pay a nasty new tax penalty, they will feel the hit on their finances. And then they come back very pissed off. You won't have enough flamethrowers to hold them back. This will bring the risk of a repeat of the 2010 election season.
"What else will the Government order me to purchase from a private corporation, just because I happen to be alive" SOMEONE will answer that question. That someone will probably be a Republican administration that seeking to capitalize on that decision.
