You can't give up privacy to get security. Privacy IS security. Privacy depends on the ability to keep secrets, and that does not happen unless you have good security in place. So in order to give up privacy at all, you must first give up some security. That's why it's silly to suggest that giving up privacy will ever result in more security.

PS - You might gain a different kind of security by giving up privacy.
