This isn't true!  The US government does not force you to use the dollar and other local currencies are used in some places.

I see you did not even attempt to defend your claim that bitcoins would be worthless under this proposal.  I am genuinely disappointed by the defensive response to this thread.  Maybe the OP was a troll but I am not.

And yes I actually think it's very likely that a new currency will emerge from this morass.
