Nostr should be sold to activists and independent journalists as their identity backup.

Nostr is where you post link to new social media accounts when previous ones get deleted.
For your most loyal followers / other activists and journalists can always find you.

Where you share stories exclusively that can't be shared on your other social media because of censorship.

Just forget zaps all together, none of these people are monetised on social media platforms, they aren't motivated by money.
A couple dollars a month for preaching to the choir is not appealing to them.
