Given the variety of agreements on international intellectual property law such as the Berne Convention, WCT, TRIPS pushed through multinational organizations like the WTO, the only country in the world with 0 copyright is the Marshall Islands (excluding audio-visual media regulated by the Unauthorized Copies of Recorded Materials Act, 1991). Even North Korea has life + 50 years.

Some countries decide to leave their copyright laws unenforced (or selectively enforced if they don't like you). Not much choice for people who don't agree with copyright law itself though.
