I don't understand your argumentation against stereoscopy. It is how you see the world. Even your suggested "dream device" would be stereoscopic device. You can't run away from it. Besides even if the device something like you suggested will ever be developed, there will be those few guys who will complain how it is not real VR and how you need to send signals directly to the optical nerve as well as spinal chord and all other senses in order to achieve "real VR". These kind of talks are unproductive. Better try to develop your version of VR instead of complaining about current best.
