Immersive Audio and How to Achieve It

... A live performance "immerses" you and frees you up to move around the room, the dance floor and still be immersed ...

Your statement reveals you have very limited experience with live music performances. You might be surprised to learn that many of the sonically best music venues have no dance floor at all.

Would you concede that the best performance spaces address acoustics?

You can address the acoustics of your dance floor all you like, and that's fine by me. But as I noted, many of the sonically best music venues have no dance floor at all. You might want to visit a few if you want to understand acoustics and "immersive" sound.

... ALL studio recordings are HIGHLY processed ...

Nonsense. In fact, some of the best recordings available are only minimally processed.

... Stereo means two, as in two ears, two auditory senses ...

No, it doesn't. Stereo means "solid," or three-dimensional. It's Greek. Hence, we have two-channel stereo, surround sound stereo, "immersive" stereo, and the like.
