You have good points! I would love to work like you described in 3D space. In meta horizon world you are able to do that. It’s not in my country yet
Try TiltBrush / OpenBrush, and Kodon. Another app to look at is Tvori.
Apple's big problem when they previously tried to "do" VR, is that they saw it as a place to consume content created in tools on a 2D computing experience, whereas after usng 3D tools, it becomes clear the opposite is true - 3D workspaces are the place where people will create content for 2D consumption experiences. This is what's already happening in cinema - cameras are VR tracked, so that a live rear projection background can be used and captured in camera, without chromakeying.
