NFTs also annoy me because it's literally the worst part of art industry - "buying" the "rights" to a piece of art so you can turn it for more cash later on, and not as an appreciation of the work. Bored Apes might be one of the few exceptions where people are doing it for "bragging rights", which is infinitely better because you're buying it to say you own it, much closer to normal art purchases.
You are buying the rights, but they're rights that exist in a pseudo-legal system that has no enforcement and isn't recognized by any existing legal authority. Some kind of enforcement could exist one day though.
For instance, it's possible that your house in a "metaverse" might only display art for the NFTs that it verifies you own.
Doesn't mean this can't be done, but in each case I've looked at, granting of rights (and which specific rights do we even mean?) is not happening.
Further more there is no obligation for anyone to do anything with the image linked to the NFT your the holder of.
