Please go an look at the US constitution regarding legal tender.
EVEN the law makers don't care about the constitutional-law.
And now you come and tell us you are an "libertarian".
You are not.
If you where you would let people decide for them self what is "legal" and what is not.
You are allways free to use what you want. That is liberty!
I am a law-abiding libertarian. Yes, they exist. I promote libertarianism, vote for libertarian policies, etc. But I do not tarnish libertarians' image by making it seem like they are all criminals.
So, you're one of those idiots who says that something should or should not be done based on the law. So, if the law says it's illegal to fund Wikileaks, then it shouldn't be done. If the law says you must be executed for being gay, then that's obviously okay!
I don't agree with the law. I believe this stuff is morally unacceptable. However, I abide by the law.
