I guess my response to this is that basic music theory is roughly equivalent with basic acoustics, has more bearing on generalized musical practice than what you are implying, and that even reading sheet music is an abstraction that requires foundations in a musical culture that has a prerequisite of certain assumptions that may not actually hold.
If you listen to CPE Bach knowing that each note can be bent (as on a guitar, because it is a clavichord), then the written music makes more sense because each note can be tuned to be harmonic with the fundamental. The sheet is just a sketch. The presumed required bend in each note totally changes the expectations of the key it is written in.
Or, if you are listening to a gamelan, then the beating of notes becomes an essential rhythm of the instrument, informing the tempo of the ensemble as a whole.
Music theory is a combination of acoustics and music history, but the acoustic part is more fundamental/basic. Like knowing "Clueless" is based on "The Taming of the Shrew" is informative, but the fundamentals of quality movie making or movie consuming do not require you to know anything about Shakespeare.
