It's all about speed and efficiency. A 3D environment might be the most intuitive one in the long run but it will never be faster because you either are moving through 3D space just to manipulate a virtual object, or you're waving your hands around in AR/VR space to manipulate virtual objects. While on the other side I'm simply moving my fingers and hands swiftly across a small surface to perform the same action.
