Isn't it possible that this will be the case on nostr in the future? I know it's a permissionless protocol, but couldn't it be that the only way to get anyone to listen will be through a paid relay?

No I don’t believe so. Running a relay will be as easy as open in an app on your phone. Relays will auto locate each each and know just the right ones to connect to.
This will ensure free communication.
