Yeah I agree, you don't use the same wallet address everytime, you use a fresh key if you like each time, but the overall amount is under the umbrella of whatever your set-up is.

Nostr is using the, this is the only key used by jack, jill or whoever and that is the verification of the said account.

Like has been said, losing the nsec, or entrusting it to a bunker service is not ideal.

But I guess there needs to be privacy and truth at the same time which is obviously tricky to balance.

To the OP, I'm just starting with Pubky, I got an invite code from JC, and it's all new, just working things out.
