You’re focusing too much on the defaults. There’s nothing stopping a third party from capturing or building a bunch more scenes and selling them as an app. Probably as a subscription. I’d be surprised if there’s not someone right now trying to make or repurpose a procedurally generated forest.
And in principle, it would be possible to have a weather and environment broadcasted through cameras in any place in the world. And there are already VR games that get it quite right.
