In that case, another agency would simply pick up the slack.

I'll propose an alternative idea. Repurpose the NSA towards hardening communications infrastructure in terms of both reliability and anonymity. Use them to help test software for vulnerabilities or even design better software.

At this rate, realistically, how many years until they (and their brethren) are the power behind the throne. In a surveillance era, some version of GoogleCIA will have the ability to move or alter elections in any way they like. It's always for the best reasons of course.
