That's yet a different issue. Watching an old episode of Seinfeld does not violate anyone's privacy.

Theft: you have a painting. I took it.

Copyright infringement: You painted a painting. I took a picture of it and sold/gave away prints to all my friends.

Violation of privacy: I got into your phone and looked at all your dick pics.

Warrantless search: The police got into your phone and looked at all your dick pics, possibly finding evidence of a crime.

They are different issues which can look similar at times, but are actually completely separate. Pretending like they are is just adding muck to this discussion.
