Indeed, we have binaural hearing because we have two ears, and we can get directional cues. We'd be in a sorry pickle if our hearing was merely stereo!

You might want to look up the actual meaning of wordshttp://history.sandiego.edu/GEN/recording/stereo.html
1916 - Harvey Fletcher joined the Research Division of Western Electric Engineering Dept to work with Irving Crandall on hearing and speech, was director of acoustic research at Bell Labs 1927-49, built the Western Electric Model 2A hearing aid and a binaural headset in the 1920's, published the widely-read book Speech and Hearing in 1929 that analyzed the characteristics of sound. Fletcher would lead much of the research on binaural, or what later would be called "stereophonic" sound recording, at Bell Labs.Binaural is a subset of stereo. To say Binaural isn't stereo is like saying Blumelein isn't stereo or thre track mixed down to two track isn't stereo. If it is played back in two channels it is stereo.

There is no binaural system that isn't stereophonic. there are plenty of stereophonic systems that are not binaural.
One does not establish a logical hierarchy simply by the number of instances.Stereo simply doesn't work the same way as binaural.
In real listening, when we hear an instrument playing or a singer singing in a concert hall, we get the direct sound from the instrument or singing plus reflected sound from various directions delayed by varying amounts of time and differing in frequency content compared to the direct sound.
Stereo reproduction provides direct sounds and recorded reflected sound from two or more locations creating a phantom image located between the speakers as a rule. The sound of a single performer reaches our ears from each speaker from a different direction and travels around our head to reach the ear shadowed by our head. The sound from the different speakers is mixed by the time it reaches our ears. This is not what would happen live, where the sound of the performer originates from a single source. I illustrate using a single instrument or performer for simplicity.
Binaural recording mimics the way we hear. When recorded, sound is mediated by our head and ear structures the same as if the person were sitting there, and when played back through high quality headphones, the sound mimics the way hear a live performance. Stereo does not.
No useful purpose is served by confusing stereophonic and binaural reproduction.
