Yeah, it's not realistic to expect content creators to be nostr-only in general. Even the middle/biggish  20, 30,40k followers on twitterx struggle to make a living, can't convince them to join nostr with 10k users in total, who may or may not even care about their particular topic/project.

perhaps more realistic to promote multi-platform publishing with nostr as an option. not sure if that already exists?

Nostr marketed in the short term to people like this as the perfect 'just in case i get deplatformed again' option(?)
