[thingification]

Can you explain why it's necessary to prevent people doing those things, or to impose a totalitarian state, in order to prevent identification of random citizen x by random citizen y?

It seems what's actually needed to prevent that is controls on the creation and use of large databases in order to identify faces (except under some list of acceptable uses). People who work in IT often express disbelief that laws like that could work. In fact, factors that humans understand like scale and intent are an important part of law, and laws written in those terms are commonplace.

Re villages: another thing commonplace in the past was brutal violence. In the past, it was obvious that brutal violence was inevitable. Then, we made it illegal, and it largely stopped. We should do that again, in this case.
