Another good post. IMO, you are making a similar point, in the IoT domain, to the one Benjamin Mako Hill made a few years ago in the email domain: https://mako.cc/copyrighteous/google-has-most-of-my-email-because-it-has-all-of-yours .

The point is: even if some people behave in strongly privacy-conscious and privacy-respecting ways, other people's failure to act similarly responsibly will almost certainly compromise their efforts substantially.
