I actually find it a bit humourous how excitable people get about their nsec.
God forbid someone steals your identity of your identity of posting stupid notes and memes on nostr.
I can't think of anything that is more "throw away" than a nostr nsec.
I raw dog my nsec all the time. I don't really care. I run my own relays and I have nip-05
No reason to be precious about it.
