The main inherent reason why 3D isn't as great as it seems is that human vision can't see through solids. We don't perceive an entire 3D volume, we just perceive the part of its surface that faces us. We can obviously get more information from stereoscopic vision compared to 2D, but it's not a full other dimension of complete volumetric data. We mostly see a 2D surface with some depth information.
