It doesn't, but that also not what's valuable here. Take the recent grumpy cat NFT as an example, what's being sold is just an the original grumpy cat image except the NFT creator is verified to be the cat's owner. It doesn't give the purchaser any rights but it still sold for a decent amount. What's valuable is that it was created by the owner, not any rights or control.
