> If first sale doctrine is ever fixed, your friend could sell you their copy that way.
Yes, but NFTs claim to get similar effects without changing the law.
> I don't know why all your examples involve third parties stamping sweet nothings onto a piece of paper.
The third party is the blockchain. Because the blockchain can't enforce that you actually hand over real ownership rights to correspond with the NFT ownership.
> An NFT needs to have some kind of rights in the contract or it's a scam. Notably you at least need exclusivity!
If I own a piece of paper my country's legal system will accept as meaning I own something, why would I also want a piece of virtual paper that a bunch of people on the internet will accept as meaning I own some sort of rights to something.
> But that doesn't make it "redundant". It's a way of making a contract, not a replacement for contracts.
What NFT can I use to make a contract that any real legal system will accept?
