After some thought, I believe that the social good argument, if it somehow came out the other way, would in fact move me to reluctantly change my mind. (Your example arguments didn't do the trick, though-- to get my brain to imagine an argument that would move me, I had to imagine a world where my continued interaction with other humans in fact harms them in ways I cannot do something to avoid; something like I'm an evil person, don't wish to be evil, but it's not possible to cease being evil are all true.) I'd still at least want a minecraft version of wireheading and not a drugged out version, I think.
