I agree but every creator has a category.

Out of 100 followers, 2-3 love him, 9-10 buy what he says, 90 followers just like him.

If the creator tries to onboard his followers conversion rate will be less than 25% 

It's a top-down approach.

We need a bottom-up strategy.

The creator selects a platform to create where the audience is.

Dancer go on Tiktok.
Vloggers go on YouTube.
Influences go on Instagram.

Example.

Bitcoiners use Nostr, so Bitcoin content creators join Nostr.
