Spinning up a Blossom server for self-hosting doesn’t seem realistic either. Do you have ideas for removing the centralized point of failure and scaling nostr hosting in a decentralized way?

What matters if you can *move* your content. With Blossom or a future spec allowing media URL changes (which is better than Blossom but doesn't exist yet) you could keep a local backup of all your media in a single .zip, and if it goes down reupload it as needed.
