What is a small percentage to you? Its extremely frustrating that there is basically no way to access large swaths of Japanese media because the companies don't think there is much market outside the country. They even go so far as to block their biggest stars on youtube. I thought it was extremely ironic that AKB's Fortune Cookie video was not watchable in the US on youtube, when the entire premise of the video was that people all around the world were posting videos on youtube doing the dance featured in the video because they had such a global reach.
Good luck finding anything but the most popular animes legally in the US. I don't think I've ever even seen a Japanese drama through a legal means.
for what it's worth, i use torrents regularly, I just don't see this reason to be conductive to the argument.
If a title is not available in a region, the copyright holder implicitly doesn't care at all. They care about piracy of their goods in regions where it's legally available for purchase. So sticking to arguments that revolve around that seem to make more sense, otherwise you are "preaching to the choir" as it were.
