What other tool?
The fact that it defines permissionless cryptographic keys for ownership is the inherent property that makes privacy with nostr even possible, I see no other equivalent.
Which makes it all the more important for us to recommend it to people in search for it, albeit with the necessary caveats.
That doesn't make much sense. There are tons of protocols that define cryptographic keys for ownership. You could use any of them to build a privacy-first stack. Nostr has a lot of benefits over them for other things, but in the privacy realm it doesn't really add much compared to these other protocols.
Maybe, but that is all you need to build a verifiable, open, privacy stack, and it is an inherent property of nostr. I think we've reached the point in discussion where we're just arguing semantics, which is fine. I can agree to disagree here.
