To expand on this, nostr is there for the most desperate, much like bitcoin to be honest.
It gives those who would otherwise have no voice the ability to communicate, just like bitcoin gives the unbanked the ability to transact.
I agree 99% of people won't do all those things, but also 99% of people likely aren't desperate enough right now. If/when that time comes, nostr will be here for them. Things like that don't happen in a vacuum. And when it does happen to a given population, that disenfranchised group alone will be enough users to make nostr "worth it" and appreciated.
I noted this a while back but I think its appropriate here: nostr doesn't have to be big, to be big.
