My thoughts exactly, let the most power hungry totalitarian states ban it, then the west will end up playing the "we don't want to ban bitcoin, only repressive regimes like China or Russia do that" political card, which will almost certainly boost widespread support in all the countries that have not banned it. Besides, how will russia deal with the situation the FBI was in recently when the silk road went down, a massive heap of wallets full of bitcoins. They will most likely end up selling them, they would not throw millions away.
