I am actually a believer that NFTs should be a thing but I don't believe the problem has been solved yet, collectable cards on a piece of cardboard has a lot of problems, if nostr or something similar could handle digital collectables it would be great, I agree to keep it the fuck away from Bitcoin and even Blockchain if possible

Nostr CAN handle digital collectibles because of the cryptographic PUB/PRIV key nature but it's not about making collectibles to the spammers, it's about leaving a mark on a system that everyone can use.
Nostr is just as immutable as Bitcoin but because you'd have to actually naturally generate value in a social marketplace, they don't use it.
I think the problem with nostr and digital collectables is they have to be stored on a relay somewhere, nothing on nostr can be guaranteed to be here later, we just think it's likely that some relay will have the information
