It doesn't matter. Protecting privacy is too big a goal.
In the end, why does the NSA do what it does? To get specific, actionable intelligence. Everyone in the world's privacy is just collateral damage.
But, turn that around. Protecting your privacy (never mind anyone else's) is too big a goal. It's too easily breached. Instead, think of what specific information you feel you need to keep private, and how you might do that.
Of course, the goal of keeping specific, actionable information secret leads to the question of why you'd want to do that. A general desire for privacy doesn't mark you as one of the "bad guys". Having something specific to hide leads to questions of why? To what end? Should we be worried?
Thats why we all should keep as much privacy as possible, if not for the sake of feeling a need for it ourselves, but to help out those who feel so. It is easier for them to hide among the mass of encrypted traffic and privacy-aware activities rather than stand out there on their own, shining like a light bulb to the NSA and other adversaries.
Because it's polite and it limits the diffusion of bad smells. If you really want to see my dick all you have to do is go on chatroulette. No need to follow me to the toilet. Unless you're interested in more than just looking.
Point is not that you have an altruistic reason for wanting privacy for certain parts of your life (which I'm sure you do).
The point is that once the very act of wanting privacy starts becoming suspicious, we've moved away from a free society towards the totalitarian end of the spectrum.
