That is indeed a very good idea 🙏😱🔥👀
I would love to see some ideas from nets applied to digital art integrated to nostr : 
- proof of creation ( certificate) and a date ! So we can check a digital element is from the author we believe and the date is to prevent stealing. 
- kind of trace of ownership / selling .
- client integration, so artists can just publish notes and people can buy , full or partly ? 
— no collection management to prevent the annoying scam/spam nft  animals nightmare ( if possible).
