My basic attitude is that they shouldn't be trying to regulate P2P file transfers anyway. While it's used for illegal things by some people, it's a perfectly legitimate technology for distributing a lot of differant things.
I'm hardly, pro-pirate, and heck you might even argue that most of the usage involved here is in some way connected to piracy. However with all of the abandonware and things that are public domain out there, it's difficult to argue against what is simply an efficient means of anonymously storing and distributing data.
I think a lot of the pressure on things like P2P file sharing is because of how it affects the broadening gray area of IP rights. While I'm not into Anime as much as I used to be, and things might have changed, I look at the whole fansubbing community. Simply put you have people that take shows off Japanese TV, add their own subtitles and english translation as a hobby, and then distribute it to countries where these things would not normally be seen. There has been a lot of back and forth about this as far as IP rights go, when your dealing with material that isn't for sale in the market it's going to to begin with, and nobody is making money off of it. Torrents have been a major avenue of distribution and made fansubbing a much bigger deal than it was years ago when you had to deal with people through the mail. This kind of thing, not just with anime, but people passing around recorded TV shows (which anyone could have seen for free) at a time when companies want to sell expensive DVD/Blu Ray sets, creates a gray area of legitimate high-traffic activity, that none the less meets with a lot of contreversy and which people would want to shut down. This is to say nothing of entirely legitimate uses.
I haven't followed that kind of thing much recently, so I could be wrong about where a lot of it stands. However I believe there are still plenty of sites operating more or less in the public eye providing a lot of that material for free without that kind of pressure, leading me to believe there hasn't been any kind of legislation making it actually illegal.
In the end the problem with P2P file sharing is more one about anonymity and the fact that it really can't be regulated. That however does not make it inherantly criminal, and I think it's wrong for anyone to be cracking down on it. At the core I think is a situation where goverments inherantly fear anything they can't control. I also tend to think that businesses like ISPs who "sell out" and get involved in this kind of thing willingly are not only the lowest of the low, but also shooting themselves in the foot.
