I think comparing intellectual property theft to slavery and stealing land is where I start leaning towards the argument being absurd. The stolen books are still on store shelves. People are likely still buying them at about the same rate as before.

And as far as it being for the greater good that seems to be the promise of many of these companies. What will inevitably get in the way is greed and money, the very same reasons we're arguing about IP theft. Good or bad I see no way out of this but through at this point.
