We seem to be talking past each other.

I'm saying there is no general 2D capability either, so the existence of a general 3D capability (which I doubt it exists) is irrelevant to the question.

And that is also separate from whether VR is useful for a general audience. VR becomes useful for a general audience the same way a smartphone or a computer does: by covering enough usages that the vast majority of users will find useful applications. That's regardless of whether those applications use a 2D UI projected into the virtual environment or a skeuomorphic 3D UI.
