Right. So what is the point in zaps exactly? It seem every nostr client is really keen on implementing them. To me they are a turn off, for the reasons you said.

The point is rewarding the creators of content you like. Paying for content, so that the writers of said content don't resort to shilling shit just to be able to earn a living from their writing.
You can't yet earn a living from zaps, but the underlying incentive structure is there and it will slowly come to reality as NOSTR grows.
