I dont feel that the question was truly answered. WHY do we care? The author writes about human behavior and discusses the 'natural right' of privacy but arent natural rights just customs from previous generations. Observing human behavior might suggest that privacy somehow is a desired trait from natural selection. ie when pooping, animals are more vulnerable (maybe) suggesting that privacy somehow aids in security from preditors. Financial Transactional data privacy allows a competitive advantage on future trades.

Basically id like to hear arguments that get down to the fundamental reasons why humans care about privacy.
