> There is no sane person in the world that believes that a torrent site's primary purpose is for legal downloads.
You cannot say that. That's absurd. There are tons of torrent sites with legal content, and whose primary purpose is the sharing of legal content. For example http://www.clearbits.net.

Bypassing whatever ISPs put in place will likely still be easier than purchasing, especially given that pirated content typically has a higher quality than paid content. It's a double-whammy: paying for DVDs or CDs forces you to see ads (occasionally telling you not to pirate!), in some cases download DRMed, locked content, and usually at a lower bitrate than the pirated options.
Not only is it easier to pirate, but you usually end up with a higher-quality and less annoying product.
Edit: The solution to all of this is for the content distributors to realize and understand the situation. If they put all the high-quality content online and provide direct, fast downloads (without treating me like a criminal!) then the world will change and most people will buy content...I think.
