Not a holy grail, but definitely a peice in the puzzle of forming a more free and decentralized internet. I don't think it's a new hurdle for newbies though. You don't have to use nostr to be a bitcoiner, and you don't have to hodl bitcoin to use nostr. They are symbyotic, but seperate, so new bitcoiners don't need to even worry about it in the beginning of their journey.
