States have and will routinely harass and otherwise dampen the efforts of activists, dissidents, even journalists. I think examples of that are easy to find. Furthermore, they can't really have good privacy unless everyone does. For a general case of the harms of privacy invasion, I recommend reading relevant chapters off of Schneier's Data and Goliath. Brilliant book.
