If you're still not convinced that you should be concerned about privacy you should watch this video, in which Glenn Greenwald talks passionately about why it's so important.
Greenwald was one of the first reporters to see the Edward Snowden files way back when. He knows why this matters.

Rather, we need to be able to express ourselves unwatched; that means we all need privacy. [TED]
