"most people" is doing a lot of heavy lifting here:

(I love your work on all this, and I'm trying to be neutral-ish as we all move to the best solutions. I'm just pointing out that I find this argument a bit weak)
I don't think the issue has ever been about "seeing the balance", or about watching the public zaps going around within Nostr. As you quite rightly said, zaps are about being transparent about the fact that person A zapped person B an amount X
The privacy challenge arises when people try to swap in and out of Nostr, that's where the tracking fears start. Following the money within Nostr was never the issue; the issue arises when try to take the money out of Nostr, like using your on-chain Nostr zaps to make a non-Nostr payment
