I don't really get this argument. Putting aside that if someone wants to follow you and take pictures they can do that already, and that glass itself doesn't cause you to become that person, the worst you can experience will be in the background of someone's picture or video.
Miniature cameras have been available for years, strapping one to your head doesn't make you a stalker.
Depending on your country, you probably are being photographed all the time - if significant portion of cars have dashboard-cams (as, say, in Russia) then on the street you're likely all the time on someone's camera.
Are those recordings currently posted on Facebook or Youtube, with you tagged in them? Do those cameras follow you inside every pub? If so I am quite sorry for you.
This isn't fighting governments, this is creating the panopticon. All the public footage will be used by governments and I think you'll find that it will be much more invasive and even malicious than what governments are currently doing. Governments are mostly interested in illegal actions and are at least partially constrained, the general public and anyone who doesn't like you will be happy to use this against you in every way conceivable.
There's the gov't side to it and also after several more levels of gadgets that each give us a "new normal", we'll probably end up like this http://www.youtube.com/watch?v=SKrYHLE8mDc
