NSA-proofing is (in my opinion) a very temporary and actually kind of a selfish way of solving this problem. This is a situation where everyone is affected by legislation, cutting yourself out of the situation doesn't help anyone around you (and those you may communicate with, bringing you back into the 'grid') and really just delays the inevitable.

Everyone has some responsibility, and for any sort of permanent or at the very least long-lastic effect, people need to motivate and bombard their representatives with letters and phone calls.
