I think Nostr is a bitcoin circular economy in bitcoin's natural habitat: the internet. Pushing bitcoin adoption through communities on the web scales much better than in meatspace. Geography doesn't matter, and people with similar views and ideas can connect and economize with each other irrespective of where they are.

Another good fit is that bitcoiners tend to be creative and creators, which is a requirement for a bitcoin circular economy

And nostr is bottom-up by design so I like that a lot. I think it's going to grow and get better in waves. I should do a deep-dive into it again. It's been some time since I've had a look into what is going besides social media.
