Is it important that you buy a cup of coffee to let people know? The point is not whether it is important or not, the point is that privacy is a basic human right. Privacy is not anonymity. The way to be anonymous in the cell phone age is to not use the cell phone. But using a phone can still maintain privacy, depending on how you do it.

I wish I could not use a cell phone and still function in this grey world. I'm doing my best to maintain certain privacy. Not total, but at least some kind of privacy.
