Maybe some relays could charge microfees for connection or maybe they could charge for each note posted. 1 sat/post would be really acceptable and would prevent spam...

that seems reasonable. And yea to prevent spam makes sense. I just think you'd create a lot more resistance for adoption this early in the game.
Yes, this is basically the way stacker.news handles monetization. It sucks that people have to pay to speak though, especially if no one runs free relays. You could also have companies sponsoring relays to keep them open and free for everyone to write to.
