Nah, the Fediverse is based on freedom of association while most people live in countries they were born in and leaving one is really hard in most cases. Not to mention that ‘self-hosting’ a state just for yourself would be considered an extremism by existing states.
The Fediverse is clearly a libertarian idea.
an even better thing would be to put more emphasis on user controlled blocks.
And force your instance maintainers to deal with the amount of bigoted content they won’t be able to moderate? There’s already a huge amount of stuff any other instance would be blocked with no hesitation.
Reminds me of this comment by one of the Lemmy devs: https://lemmy.ml/comment/6744852
Technology won’t save us if we allow unethical companies to mess with us.
“Yeah, just block every bigot in existance and you will achieve a somewhat good experience”
Spammers also exist, and they can go long ways to avoid blocking by e.g. creating many accounts. There are people out there who could do this just to troll and harass a single user. If you’re fine with blocking every piece of shit there are - good for you. But it doesn’t mean it should be a norm.
