We all live in nation-states and are required to abide by their laws as a result. Though it's theoretically possible to separate currency from governments, if that's not what the governments want, it will never be legally permissible. As it is, Bitcoin operates in a legal gray area. That's not going to improve.
Most of the VCs I talked to about FaceCash refused to invest because they were afraid of the regulatory implications. But throw in some bad economics (verified as such by Paul Krugman, see http://krugman.blogs.nytimes.com/2011/09/07/golden-cyberfett...), a catchy buzzword or two, and some political philosophy, and you've got yourself an investor?
