Explain more about why privacy is essentially contested

[darobin]

This came from wide review in personal communication:

"I really appreciate how this document does a survey of relevant literature, neatly summarizing it in a short space. I'm grateful that you've read a lot of academic work and are doing the labour of summarizing it for me (thank you!). I was disappointed with how little depth of discussion there was to flesh out either the core ideas of “Privacy is essentially contested” or “GKC-Privacy”."
