Haha, that'd make you really suspect if they end up banning bitcoins in the US.
The day the US bans Bitcoins is the day I start looking for a new country to call home for my whole family. I'm not saying it's not going to happen... but if it does, that'll be my response, and I'm sure I will not be alone. It'll be interesting to see how the world's governments are going to deal with a currency system they cannot (easily) tax.
