Perhaps a less disruptive change would be to maintain copyright protections the way they are, but attack this at the penalty level: basically enshrine the idea that
> "X was not available for purchase or streaming in a DRM-free format in my country at the time I got a copy of it from a torrent."
Would be a valid defense for personal use, capping penalties at 1$ or so, without opening the public-domain box and opening the field to companies instantly cropping up to snipe a 5-year-old TV show the day it goes free, and resell it.
