Obviously, the idea is to not disallow having someone take a photo of you as a background, passing figure as they take a front-and-center photo of their family, but not allow you to be the main subject unknowingly and especially when you object explicitly.
On the other hand, a photographer still owns the copyright to a photo, so a subject (including in a portrait) cannot claim it or distribute it without permission even if they can potentially stop the photographer from distributing that photo.
IANAL, but you are not by default allowed to use anyone's "likeness" for your individual profit.
