It's like the war on marijuana. When you have millions who want your "illegal" product, and when it's hard to justify it but can only be explained by stupidity or monetary greed of the already rich and privileged, then it's not exactly the same. But they use the same techniques.
Weed is a plant, it will grow if you plant the seed. P2P, as well, is very easy get going.
