I think Privacy is difficult to implement in a governed country; states will likely want some sensitive data to carry out operations (internal, civil, and global). Surveillance and tracking are tools for control, because they can retrieve hidden data. States usually want control, so they typically employ surveillance.

I think privacy will only be fully supported in an anarchist country; the lack of hierarchies (and states) mean privacy can flourish; because there is no power that can involuntarily control the people; so there is no involuntary control.
