Oridinals is a terrible brand.  But buried in there are some pretty good code.  Namely, that prunable OP_RETURNS can cheaply create colored coins without bloating the block chain.  Take that bit and combine it with nostr.  Then you have lots of good solutions, with different trade offs. 

- on-chain / high fees
- lightning / low fees, requires config and maintanance
- cashu / low fees, requires to trust a mint
- liquid / low fees, requires to trust a federation
- colored coins, rgb, tarot / requires to trust an npub
