> The more utility in the item, the less I care about a separate ID number associated to it

I completed agreed to the point you were making and then I got reminded of sneakers. They are supposed to be of high utility and yet 'limited edition sneakers' command a high price and are never used (in fact they lose value on being used).

I think other threads in the discussion point out the difference between the price people pay for 'owning' an artefact versus 'enjoying' an artefact. In the music case also, I can totally imagine a successful artist taking out limited NFTs on their music and their super fans buying it, trading it amongst themselves. Most people who want to 'enjoy' it won't care but I guess a case can be made for die-hard fans wanting to own it.
