The DMCA prohibits defeating a technological measure that restricts access to a copyrighted work. So, if some company or individual somewhere releases a copyrighted text, and they "encrypt" it by running it thru rot13... then yes, if they can convince a court of law that rot13 qualifies as a "technological protection measure," then it would be illegal to decrypt that document.
I don't know what the qualifications are to be considered a "technological protection measure," tho. If the DMCA includes minimum requirements, then rot13 may not meet them; if it doesn't, then it might be up to a court of law to decide if something as trivial as rot13 could reasonably be called a technological protection measure.
Obviously: IANAL

That means that you could use rot13 and be safe because DMCA forbids breaking crypto? Or did I missunderstand something? (I don't live in USA, so DMCA doesn't mean anything to me) "
Yes. Someone once got sued over 'decrypting' base64 encoding. I don't recall who or for what, and I cannot remember if they won in court, but it happened. A lot of people cannot afford to go to court and prove that it's a ridiculous claim, so companies can get away with this kind of thing.
