I agree with those statements.
I offer another view from a person that aspire to build his own instance/community. For me feature N° 1 is having already solved the network effect problem i.e. having already all NOSTR users on my instance.
Then I would like to shape all of those users into my ideal community. A community is made by creators and followers.

I would like to have the possibility to invite, according to my view, creators to appears has if they are local users of my instace/community (if they agree) and in turn share with them any contributions/zaps coming from the users using my instance to access NOSTR.
Creators may participate to many different instances and at the same time instances may have creators not necessarily bound to them.
