Are you kidding, with the current crop of cowards in Washington, and crooks in the electorate?
You honestly think that BO & Co. won't find a way to just confiscate it?
To confiscate it...you’d have to have a law broken or a new law enacted. There’s no law against this, and Congress won’t pass such a law. And to even suggest you might go out and start seizing money....you’d disrupt the entire business sector and throw the economy into a fair-sized depression. So I don’t see a problem with a tactic like this.
