It's not a matter of availability of technology, but essentially of values - for example, a technology for murdering people cheaply and effectively (guns) exists and yet murder is not ubiquitous precisely because people agree that it's wrong. The privacy folks are just arguing that being under near-constant surveilance when in public space is also wrong. I'm not saying that I necessarily agree with them, but saying that if technology exists, then its use cannot be (to a large degree) prevented, is just incorrect.
