It should be probably done by Theymos, that's if it should be done at all and it should be in a way that, some of the credit from its auction in percentage is always redirected to the forums treasury. It could be a thing, just as the cypher or crypto punks that meant virtually nothing transformed to mean something significant in NFT.
theymos won't do that. He will not break his reputation to join NFT on behalf of satoshi or the forum.
Furthermore, the forum does not need money from donation so I can't imagine why he do this with NFT.
