This is still solved by certificates, I can make my own self signed certificate that says it me and sign whatever I want. The only thing that crypto “solves” is over the wire man in the middle attacks, which aren’t even really a problem in the modern internet
How do I know you haven’t made 10 copies of that same certificate and sold 9 to other people?
If it was an NFT I could see you issued 9 other copies of it before I was approached with the sale. Any other way I either have to place blind trust in you or rely on a 3rd party to handle the issuance/transaction

Why would I want that, I’m not selling you anything
