The fact that the NFT sold for more than the original print after the act suggests to me that the "sacrifice-value-transfer" is not an exact 1:1 process, since the resulting NFT had a different value. Yes, the owner is probably delighted that the NFT is worth more, but then I'd argue that "uploading a physical object's value to the digital realm" is no longer the right way to think about this.
