There's no arguing the emotional appeal of the right when they complain that the individual mandate in the healthcare reform act amounts to, for the first time in human history, "taxing breathing" (although they use the phrase for other things they don't like too). They are so good at that kind of stuff. Wow, how "unfair"!
But let's be honest: Yes, you can "choose" to not pay income tax by not making any money, and you can "choose" to not pay property taxes by not owning real-estate and also not renting from someone who owns property, and you can "choose" to not pay sales tax by not buying anything, and you can "choose" not to pay fuel taxes by never going anywhere in motorized transport or using anything that used motorized transport.
But no one willingly chooses that life of extreme poverty, privation and isolation to not make money, not buy anything, not live anywhere and not use anything.
So, take a deep breath, the "moral" argument they are making simply does not hold water.
