Nsecs are not keys to a Nostr account.
There is no account.

That is why it is impossible to delete a Nostr account. Can't delete something that doesn't exist.
Even Apple doesn’t understand this.
Hardly anyone does.
Once this clicked in my head, and I realized how many problems it solved, I understood what a game-changer this is.
What you can delete are the events signed by the pen, but not the pen itself.
The pen is just strung-together letters and numbers and you can't make a string stop existing.
All you can do is put the pen down and walk away.
