You are wrong, you are basically saying "black cats exist therefore cats can't be tabby", there are plenty of preservation initiatives that preserve works in different forms when the original media can not be practically preserved or displayed. Yes best practice is to preserve as close to initial state as possible, that does not mean that when you cannot feasibly preserve the work in it's original state (with digital it's often due to drm) that you just say screw it nothing we can do but chuck it in the dustbin of history.
