West Virginia may well be more interested in banning Google Glass because of the prospect of police behaviour being recorded. Cops don't like that sort of thing, no matter how legal
it may already be in the US.
More generally, any sufficiently determined government - or suitably empowered individual - can already strip you of the illusion of privacy at will. For one thing, the privacy of data transmitted over a public network can be subverted using the right technology; this includes, in extremis, the judicious use of
the humble rubber hose where the law is either insufficient or irrelevant. Similarly, the privacy you take for granted in your private life will disappear with a few carefully executed search warrants (and/or applications of the rubber hose to yourself or to other people).
In short, the only place where one may have some hope to complete privacy is inside one's own head. And even that may not be enough.
