Yup. If your father dies, and leaves you a Rolex, but does make a way to give you access to the keys to the nft, would the Rolex stop being authentic?

When we are talking about digital proof of ownership of physical goods, any solution that can fail synchronization of the record due to entirely foreseeable events like death, ownership disputes, etc is a failed solution.

Good remark. I think it is simpler to just use a public blockchain that having Rolex properly build "open" cloud services to do that and maintain it themselves over the long run.
