I had a similar thought a few years ago when trying to think of "useful" uses of NFTs. It could be great if I could buy music, etc and then play it on any streaming service via some sort of proof-of-right-to-play mechanism.
It will never happen. Why would the future platform owners, or especially separate service owners, want to let you enjoy the benefit of their hosting costs when they get nothing?
Imagine Spotify being able to continue streaming you music that they no longer have access to, because you "the user" still have individual rights to the music.
Thwn, you can stream your own music and Spotify's music side by side.
And, it's a double win, since they're not paying an royalty fees for a single user streaming music they already own.
