I'm not whomever you refer to as formerly supporting bitcoin here. I'm 45 if you want to call that old. I'm a conservative Christian (I guess ultra-conservative, because Free Republic strikes me as an increasingly liberal hangout over the years.)
I've never done drugs of any kind, and the amount of alcohol I've ingested in my life I could easily carry in a couple jugs.
Claiming bitcoin is unconstitutional just shows how little you grasp of the Constitution or the conservative perspective on it. The Constitution is a charter document authorizing the existence of the federal government and granting it certain powers. The constitution places limits on government, not on private people. If I'm not an agent of the government, it is literally impossible for me to violate the Constitution, for example.
So a currency not authorized by a government may be declared illegal by it, but it can never be unconstitutional. It would only be unconstitutional if the U.S. government had created it in a manner that violates the Constitution.
Now, you may wish it would go away. You might wish gold would all vanish too. I don't really understand why. From a conservative perspective a currency free of Federal Reserve influence and manipulation is a good thing. It is hardly consistent with the principles of liberty to ban everything you don't like and demand everyone be coercively forced to only use your debased, dishonestly managed dollar currency.
Bzzzt. Wrong.
Your myopic view of the Constitution actually only describes the BILL OF RIGHTS. There are defined powers of the federal government that are not granted to the citizens, such as coinage and treaty powers that are outside the Bill of Rights.
You should try reading it in it’s entirety, like all of Section 8 and get back to me. Let me know if you think private citizens can do any of those things, such as regulate trade with foreign nations and exercise tariffs. Then, to further make my point, go try these things and let me know how you hold up.
Good luck!
