I get what you are saying, and agree with you in principle... but the problem is, I am none of those things. I have none of the qualities that I need to hide from anyone, rather neighbors or the government. While it kinda feels creepy to imagine myself being listened to, I can't imagine any real consequences to my private conversations being heard.

However, I know that there are lots of people who do have those things they need to hide, and if only the people who need to keep things private work to keep things private, than the very fact that they are keeping things private becomes a risk factor.

Just like how part of the value of https everywhere is to prevent encrypted traffic from standing out, everyone maintaining privacy helps prevent people who NEED privacy from standing out.

Of course, as an individual, there is a cost for demanding that privacy - I lose out on the benefits of things like the echo and facebook. And since I am not an individual who needs privacy, there is no individual incentive to maintain it. It is a bit of a collective action problem.
