Totally disagree. Protect your privacy. There is strength in numbers.
Small disclaimer: I'm not an American (which is why I'm even more pissed off at this whole situation than I'd be if I were an American -- I've lost complete respect for the US government over this) so obviously the NSA has no interest in showing up at my door. And if they would, I seriously doubt that I'd be doing anything wrong by slamming the thing shut in their faces.
