Valuable.
I think you covered a lot of the main reasons and this is definitely a current topic the last few weeks regarding Nostr. I was thinking more about Nostr than Bitcoin when reading your points, as it has more to prove. Timing is everything and Nostr isn’t going anywhere but the reasons to move to it are amassing quickly.
I’m still 20/80 with Nostr/Twitter, so could do better. I have a likely nonsensical fear that I’ll miss out on something if I remove Twitter.
