A related thought experiment.
What if Google or Bing build an image search service based on the face recognition ? If you don't like that idea, how about doing that for celebrities and public figures? If you are ok with one but not the other, what would be a good line distinguishing them and guiding principle? If you are not ok with either or ok with both, why?
More I think about it, more I lean toward allowing both, but I can see why people would not like it.

Because celebrity by definition requires trading privacy for fame, and is almost always a decision.
We need a new legal classification for "public, but not accessible by everyone in the world for the rest of time" information, which is what most regular people assume or desire for themselves.
