Really? As far as I know Bitcoin is border less. A lot of countries are Bitcoin friendly and the best way to f#@%$k with the politicians minds is to take away their power by taking away the tax money that pays for their salaries.

The Prohibition in the US has shown us the solution, when the USA start to ban Bitcoin. The black markets and underground networks will pop up like crazy and it will be decentralized, so they will not be able to shut it down.  

People will simply earn bitcoins online and then shift those bitcoins to people in Bitcoin friendly countries to convert it for them or they will have a TAX free Bitcoin holiday in those countries. All that TAX income will be lost for the US government, because they will not be spending it in the USA.
