True. It makes me at least think about what other options there are in terms of resiliency for user accounts. Right now we’re back to the wild west days of the internet where you might not be 100% sure that your provider is in it for the long haul. There were so many random email hosts in the 90s and early 2000s with vanity domains. Now, it’s rare to see anything other than Gmail, outlook, iCloud, or hotmail for personal emails. People congregated around the big companies. That’s what worries me about companies like Meta and Twitter getting into the fediverse
This got me thinking a bit, and I had this whole long post written out. Turns out someone else had a very similar idea to what I was about to discuss regarding public/private keys:

This approach is interesting because I was thinking that you would need a trusted server to host the public certificate. But maybe that isn’t the case so long as you keep a copy of your public key. As long as you have your private key, you would always have proof that a post made using your public key was from you. Even if someone tried to impersonate you, they wouldn’t be able to sign a post with your private key, which means they wouldn’t be able to link their profile to your account. Your public key certificate effectively becomes your identity and your private key signature is your “password” proof that you are the person associated with that public key.
If your main instance goes down, you could use your keys to create an account on another instance (assuming that’s permitted). Or you can create other accounts like the article describes.
On its own, this keeps your identity intact, but not your post history. It could be designed that your account on one instance references your account on all the other instances it knows about where you have an account. Then a post history could display data from multiple servers, or at least link back to your profile on your other servers.
But if a server goes offline, your posts do too. I just don’t think there’s a great way to manage that.
