Agreed on everything except for two things.

Its power, however, does not lie in being the only possible description, but in being one of the few based on primarily musical concepts, where the acoustic "justification," although coherent, could even be merely accidental
Tonality, understood as a "primarily musical concept," explains only one part of the structuring of musical discourse. When one wants to explain the rest (form, rhythm), one resorts to extramusical paradigms such as grammar (parenthesis, phrase, period), logic (motive), narrative (development). And this has been the case since the 18th century (moreover, the reference to grammar can be found as far back as antiquity). Therefore, be careful not to focus only on tonality while excluding the rest: even (indeed especially) in the classical-romantic repertoire.

Music can be explained and understood in many ways, but its aesthetic content can only be explained musically (that is, through musical concepts).
Why bring pleasure into it? Pleasure has nothing to do with phenomenology, nor directly with aesthetic content.
