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.

That's an invasion of privacy and violates all kinds of laws and ethical standards.

If you reproduce my song without my consent, that's a violation of a very specific law which allows me a temporary* restriction on your rights. The ethical question raised, I think, is of a very different nature.

*temporary: used to be ~20 years, now is until 70 years after I die.

I'd say that by simply copying and reading those emails and financial records you haven't done any harm. If you've used the knowledge gained from those documents to deprive someone of their finances(theft) or any such malicious action I'd say you've harmed the owner of these documents.

Disclaimer: I do not condone piracy, I just believe you've made a logical fallacy.

These arguments always comes up in these types of discussions. In reality though personal information has far less protection than commercial information. If you take nude pictures of yourself you might as well keep your credit card in frame, since that's essentially the only way someone would be sentenced for copying them later.

No. If you begin committing identity theft, Yes.
