To have a high trust society you need to know who you are dealing with. That's why we don't cover our faces when interacting with others or walking around. Same with driving. If anything there is too much privacy - we should know who drives irresponsibly, is a danger etc.

Privacy is about being in your home away from others, correspondence etc. Once you are interacting with others it's not a feature.

Unless we are agents of certain law enforcement agencies...
