In the case of Autoglyphs there actually is no URL involved. The instructions are stored immutably in the smart contract. However that is besides the point. How is the mode of ownership of this wall drawing different? The physical piece can change or disappear. What matters is who is recognised as the owner of the artwork an immaterial sense, as evidenced by the certificate. The owner cares about the piece of paper but not because the typography is so sweet. The piece of paper is not the artwork. The piece of paper is a token.
