Nothing is stopping you from posting whatever it is you think would be better. Nostr is very young and has been worked on by almost exclusively Bitcoiners, who are not crypto bros. Those terms mean completely different things.

Human society can not function in a healthy manner without healthy money. You dont have to be interested in human flourishing, but some of us are.

You're free to watch Netflix or whatever other garbage is on TikTok, etc. Or you could start contributing whatever it is you value on Nostr. You're here very early. Expecting to see much else is absurd. Nostr is a protocol. You can post whatever you like using it.
