Why Doesn't North Korea Copy Megaupload.com?

Megaupload.com is out of business, but not because their business model failed. The founder, Kim Dotcom, seems to have made hundreds of millions of dollars. His only downfall was basing his business in a country with friendly legal relationships with the US government. So, why doesn't North Korea (or another pariah nation) enter the illegal file sharing market? They'd get a huge inflow of foreign capital for minimal cost and no risk of arrest.
