This UN declaration doesn’t seem to establish an enduring definition of privacy.

Hayek offers a significant observation that things that work among small orders, like a family, don’t work when applied to a whole city. It speaks to the gap between a single police officer seeing something and a city-wide camera crime detection network.

  Part of our present difficulty is that we must constantly adjust our lives, our thoughts and our emotions, in order to live simultaneously within different kinds of orders according to different rules. If we were to apply the unmodified, uncurbed rules of the micro-cosmos (i.e., of the small band or troop, or say our families) to the macro-cosmos (our wider civilization), as our instincts and sentimental yearnings often make us wish to do, we would destroy it. Yet if we were always to apply rules of the extended order to our more intimate groupings, we would crush them. [Friedrich Hayek, The Fatal Conceit]
