>> "Jane goes to a party but doesn't want anyone who wasn't there to know. Jane's friends post pictures of her at said party. Now everyone who checks Facebook before Jane sees that she's been tagged in these pictures. Until now, Jane's never really considered that she should screen tags for approval first."
There are privacy settings for this (which I use). You turn on an option that all tags (photos and posts) have to be approved by you before they appear on your timeline (and thus visible to your friends).
I address this. It was something of a weak example, but I do mention that Jane realizes her privacy settings were inadequate, at least for tagging. It's already too late at this point. That particular example was one of oversight on the part of the user. I considered it to be a good starting point.
I'm betting most people don't care about this (this is what I see from my friends anyway). They want to be tagged. Therefore it makes sense that Jane would have to enable it. There's no point inconveniencing the majority of your users to satisfy the minority. If you really care about your privacy the first thing you would do using a service like Facebook is check your privacy settings.
