The problem is that most of these services are very clearly trying to argue that you don't own these things. I don't pay for Disney+ thinking I now own the legal rights to everything on there for all of time, or even that they'll be there for as long as I'm subscribed.
But NFTs are being pushed as if you actually legally own a copy of "something", even though you aren't actually buying the object behind the NFT. The rights that ownership entails are so lacking with NFTs that I don't understand why people seem to think they're one and the same. Buying an NFT does not grant me the same amount of rights that "buying" an object should.
You can argue the same shit for in game items. As long as the game is playable you own that item. Or digitally purchased games. You don't own the game and all the company has to do is delist it and you don't have access to it anymore. Yet people want to drive the narrative that they should be able to re-sell their digital games as used games.
