I don't see how that follows. Avant-garde music of this type is basically an NFT already. All of its value is in the novelty, none is in the aesthetics. The meaning of the piece is completely externalized to the identity of its author and the history of its composition and cannot be derived from observing the piece itself. That describes NFTs to a tee! The only thing missing the layer of cryptography on top.

That's painting things with a broad brush and a wrong one at that.

Ironically, there's plenty of avant-garde art that is 100% about the aesthetics, to the point people complain they were "made without technique".
