Im not doubting another site will pick up the slack, but the internnet is still in its infancy, and history wont always repeat itself.
I think its still unknown whether or not the free and open net will always be, and with it being easier and easier to steal pretty much anything, somethings gotta give. We've moved past the point of just stealing music, and some movies, to a point where even books can easily be stolen.
I agree the answer to stop it is to make the media more easily accessible. Its sad that the ones who actually pay for things are the ones that have to go through so much more hassle. For example, if i buy a dvd and want it on my ipad/tablet, i need to sit there and rip it, fight with drm etc. Whereas if i torrented it, when a better version/better quality/etc comes out i can just get that. Its just sad that the pirates do it so much better.
My guess is that for now, the industry will not innovate and will try to punish offenders. Lets alll pray SOPA and PIPA never go through.
