so vitor didn't care what anyone said and he went ahead and did it. He's a hero

Probably because it doesn't confer anything of use to the Nostr protocol. It's just sats in an address. I think that trying to come up with some arbitrary rules around what those sats mean to everyone, universally, isn't going to work. And using it for payments is so dumb not even worth mentioning.

Simple solutions often fail due to complexity, focus on robustness.

I'm beginning to lose some of the excitement I had a few days ago about using Ark as the easy way to onboard new users. I zap you by creating a Ark tree where the leaf pays (a tweaked version of) your npub My initial enthusiasm was based on the fact that this kept the payments off-chain (unless somebody needs to exercise unilateral exit). But the bad news is that the Ark still can see the payment and will learn something about how you spend the funds later. I haven't given up on it though. In the ideal case, typical users will 'upgrade' their Ark balance to a real Lightning channel sooner or later (e.g. Phoenix). Lots of potential, but risky too So I'm happily sticking with Cashu, for using and contributing a little to dev here and there
