ELI5: Why are torrent sites and it's torrenters not being attacked/arrested?

I've always wondered why nobody, such as the federal government hasn't really cracked everyone down including its users 

I am aware of he takedowns of megaupload, the pirate bay and also demonoid (which I'm sad to see go down right now since I'm an avid user)

ELI5 please :)

Regularly going after individual users doesn't really make sense, because it costs a lot more to prosecute people than the damage you do just by downloading. But going after the *providers* isn't likely to work; torrent sites get all the protections that search engines do, which means that as long as they don't actively try to get people to violate copyright there's not much of a case against them. So there's just not all that much the government can do about it.
