It doesn't have to work in the sense of stopping an invasion of privacy. Name your governmental - or even non-governmental - organization will always be able to read any individual. The question is one of effort. In an optimal world Government would have some set of checks on who it monitors - there would be judges, warrants and probable cause. As things stand that's seeming less and less the case. In a slightly less better world the effort to monitor would be great enough that governments would be forced to pick and choose just who they're monitoring. Ideally that'd be picking bad people.
