Owning an NFTs doesn't mean you have the rights of the copyright and/or the intellectual property. It comes tricky since the regulatory issues haven't addressed that problem, so does the NFT marketplace doesn't solely address copyright infringement on any minted NFT. NFT just give you in some senses an ownership like the certificate of authenticity.

What is the advantage of the traditional system that you buy the document and receive the goods

Scarcity, the ability to see the history behind the NFT, like who was the first owner, etc, and also a provable way to own and show the NFT to anyone.
