To be clear, you can't "fix" these problems. But you can mitigate them or make it easier to recover from mishaps. That's all I'm saying. The current model is pretty much as bad as it can be in my opinion. But we are still early, which is why I think it's a bad idea to start using Nostr for critical things right now. I think people should only use it for non-critical things until it's more mature and secure.
