The issue is that if you don’t default to federation, it becomes essentially impossible for new instances to join the fediverse. A potential new instance would have to go around to every single existing instance and ask to be allowlisted, which is onerous for both the new instances and for the large server admins who would be getting tons of requests. It would also essentially kill small-scale selfhosting as a result.
I kinda of lean towards the idea of “private accounts” being a bad idea as a result, just because it creates a false sense of security. But I’m not in the target demographic so idk
