Too bad for him and his friends, encryption technology is only going to get more advanced as time goes on. Once
public key encryption becomes widespread, not only will it be next to impossible for governments to spy on their citizens, but we will achieve the greatest level of personal privacy yet seen in human history. Not only will we be freed from spying and censorship, but a whole array of restrictive government policies (licensing regimes designed to restrict certain professions and activities, taxes on transactions and income derived thereof, IP protections designed to restrict access to ideas and media, and yes, laws against certain substances etc). David Friedman (son of Milton) explains this pretty well
here.
It'll be great for decent people who are content to let other people live their lives and go about their business without state harassment or persecution; not so much for the rogue's gallery of sociopaths, control freaks, and paranoid fearmongers who control the apparatus of government.
