I assume you're speaking in terms of practice, especially under current American caselaw. Lots of things are quite wrong, even if perfectly legal.
Yeah, that's just the legal angle. It's upheld every so often when a celeb gets upset about images in the press.
And yes, a lot of things are wrong and legal at the same time. Particularly wrong is the burden of celebrity that falls on the children of the rich/powerful/famous etc.
