The main point, or why it's fine is because it's new. Losing it is not really that important right now, because being honest. We're a grain of sand in comparison. So It's not much that we lose. But extrapolate and now you have 50 million users on .world and suddenly they shut the server down. Not defederation, it shuts down. Sure you can say "oh well.. I guess time to start over" I would wager most people will be like "Nah, fuck this... I'll go somewhere else that might not implode" right now we're on the reddit hate train and hyped the fuck up. Later on those servers will be getting bigger and more expensive. Some might cover it with donations, some might not.
