Any major/minor form used for communication/currency will be regulated in the end in the name of national security. No amount of democracy, socialism, communism or any ism for the fact cannot overcome it. As long as govts don't behave like a service provider but like a ruling class this won't change. Power corrupts, anyone. Hard limits on power, individuals instead of parties, extreme transparency(including defence, yes), and war free world is the only way we ever achieve freedom. As long as we allow govts to function in secrecy, someone will not care about ethics and morals.
