The technology is there for sure, it is adoption and regulation that is the problem…

As an example a LOT of devs set up classified or jobs board sites, which then tanks when close to no one uses them. If anything gets past a certain size the also they’ll be attacked by both big tech & government.

Can it all be done 100% as a protocol extension of Nostr? Perhaps, and if so maybe a mechanism of splitting earnings between the relay and content creator would be key?

If that is built into the protocol itself there would be far less attack vectors left :-)
