There exists a term which is frequently used as a metaphor in business, technology, and science to describe situations where people copy the superficial form of a successful process without understanding the underlying principles that make it work. That term is cargo cult. The social network side of Nostr is this. It copies the superficial form of a social network without understanding the underlying principles that make it work. Fundamentally those are ease of use, enjoyability, reliability and a modicum of privacy. That's not to say these couldn't be addressed using npubs, notes, kinds, etc. It's just that few of the leading developers are willing to make the necessary trade offs to satisfy these principles.
