"1. Got a VPN privacy service with servers located beyond the grasping clutches of the NSA/GCHQ."
The government will then block those VPNs so the ONLY ones you can access are domestic and open to spying. Since OpenVPN requires specific credentials like IPs in their configurations, these credentials can be read and blocked.
"2. Used local asynchronous encryption on everything sync'd to Cloud storage, protecting everything in the Cloud whether or not the respective service actually supports encryption.
3. Used whole disk encryption on everything else, including the system partition and backups."
See xkcd and the monkey wrench, unless you're wimpy or masochistic.
"4. Stopped using email entirely, and switched to Bitmessage, pseudonymous social networking via VPN, and darknets."
Serverless systems like Bitmessage, freenet, and so on are murder on data allowances. Plus what if the people you want (or NEED) to talk to don't use that stuff or have such tight data allowances it's not an option?
"Although frankly, the way things are going, I think I'm just delaying the inevitable. Under the circumstances probably the only realistic, long-term measure you can take to defend your civil liberties ... is to get a passport."
Which is less useful a prospect when more and more countries fall victim to the data grab. What'll you do when EVERY country starts doing it (including the EU when they abandon their privacy directives as ink on a page)?
