Terrorists all over the world are using USD, thus we need to get rid of it.
Mmmmm... Yeah, flawless logic.
If anyone thinks that Bitcoin value is where it's at because all these new people believe in the "cause", you too are delusional. The rise is due to speculation and greed. Remove that and Bitcoin is back to it's very small core of followers, with a value of $5-10, at best. And that's only because it will continue to be viable as a black market currency.
$10 x 11,000,000 coins means a $110,000,000 economy. Are you really saying that world's "black market" economy is worth only $110M USD?
LOL
Just FYI: according wikipedia, black market economy amounts to at least 1,800 BILLION $ per year. Yes: $1,800,000,000,000.
If Bitcoin is banned and only "black market" embraces Bitcoin... We are going to +4 digits per coin regardless of what your dear folks at DHS, Justice Department, CIA or FBI say. In fact, if the whole world "black market" economy goes to BTC (which is unrealistic, but it's just to give you a hint of how wrong are your took-from-the-ass calculations), we would be looking at $85,000 per BTC.
Your logic is simply flawed. What about cocaine, marijuana, etc.? They are waaaay cheaper because they are banned by the US, right?
And no, people will not use Bitcoin because they believe in the "cause". They will use Bitcoin because it solves a lot of practical, real life problems.
