While I agree that 8k likely represents the limit to needed resolution for traditional TV screens, VR could use improvements beyond 8k. That is one usecase of 8k+ screens. Also, to address your storage/bandwidth concerns, I expect 8k to be almost solely an "upscaling" technology (outside some niche applications). That almost nobody in practice will stream or store 8k, rather they will use local upscaling.
