It's not a particular string of letters that one is attached to, it's the notes and the ability to continually verify they are associated with the real life human being. I can imagine scenarios where everyone (almost everyone) forgets about the nsec and npub underneath and only thinks about what notes they still attribute to themselves or stand by. I haven't thought through any particular implementation for such a thing, but have heard it mentioned that one could have a backup set of keys prepared in case of compromise and ability to dissassociate with certain notes and bring back certain others with a pointer or a digital affidavit of sorts.

I am talking about paid service that uses npub/nsec to associate your purchase and assets with you. If you have no backup way to login and verify yourself, then once it’s lost, the money and the assets are gone too. If that’s the risk people want to have, I don’t mind.
I realized how far my tangent went after I clicked 'Reply.' I think the answer to your question is yes, there are people who would want that, and decent arguments not to provide it (eventually it will be a service offered somewhere anyway though.)
I'm not one who is against such tradeoffs on principle necessarily, but do encourage corresponding education (transparency) of the actual tradeoffs - in other words customer ought have a way to learn about the decision from a maximally paranoid security perspective if they so choose - and would want that to be up front from the provider.
The model I think of that's closest to the ideal tradeoff would involve distributed trust, i.e. 3 people I trust can get me back my nsec but no one of them has the whole thing.
I went on another tangent. Twas fun tho :D
🤣 all good. I am not even going into the whole key management, not my area of interest or concern at the moment
