is why on earth governments are so hot on the idea of stopping illegal music sharing.

First of all, the music & movie industries are NOT major industries. If they withered away overnight, relatively few people would be out of work.

Second, when the RIAA and the other liars start yapping about how much money they're losing, there's the implicit assumption that if illegal downloading weren't possible, the punters would pay list price for all the same stuff. This is not true.

Third, with special reference to the FBI: terrorism is a real threat, yet the FBI feels that it has the resources to have a special unit devoted to IP-crime. Can we say "misplaced priorities"?
