1. Password manager gives you access to your secrets (key included), yes, but it does not eliminate human factor.
You may forget to add your key in the first place or you can delete a note with it without even realising that this was THE key.
This may seem like a fantasy, but if you ask people or search the web - this happens all the time.
2. Backups will be encrypted the same was as the original. So this wont's save you in case you have lost your keys.
Bottom line: the whole point of E2EE is a guarantee that only keyholders can ever access the data. Period. Lost key == Lost data. No exceptions.
