I think a funding crisis shouldn’t hit Nostr as hard as it would, say Bluesky or Matrix. Worst case scenario we can pivot Nostr into a p2p system, we sign our notes after all. But I presume the doomsday scenario can be avoided by assigning sats to the services we use, ecash stamps, paid search providers and so on. Althea Mesh has this pay per forward system, perhaps it could make sense here too.
