Fair enough, and I've considered it, but deleting my account still doesn't prevent others from tagging and posting pictures of me for the benefit of those who can identify me through name or face alone. At least with an active Facebook account, I receive notifications whenever my likeness is invoked.
Additionally, Facebook has become the defacto communication platform of the day and not having one is sometimes viewed as a social red flag (or as a lie). My cellphone # has changed three times since 2004, but the respective Facebook query has only become better at finding me. My point being, "delete your account?" is something akin to "cancel your cell service?" except nobody calls and everyone uses Facebook.
You must have a strange social group. I don't have a facebook, and have never once had a problem in anything but other websites wanting me to have one. When friends ask for my facebook I say I don't have one, tell them I don't like their attitude towards privacy, they find it interesting and we move on.
Not everyone is as enlightened as your non-strange social group. One doesn't face ostracism for lack of a Facebook account, but a lot of real social interaction occurs on Facebook and I don't presume to judge those who highly value that interaction. Those people do exist and some of them are great people.
Facebook has privacy controls for preventing people from tagging you without permission, both in photos and geotagging.
Also, I finally think it's working. Previously when I tried to approve a tag of myself in a photo, FB wanted to change the privacy setting back to "anyone can tag you", but last week it seems to have worked without changing my privacy settings.
I see you've already anticipated my response. Beyond that, it seems like every six months or so I'll discover that some of my settings have been mysteriously reset during a site update or that the introduction/consolidation of new features results in a regressive behavior that I have to explicitly disable (since it's on by default).
