Because lnurl is trash and a huge centralizing factor that pushes people to custodians. We shouldn't need DNS and webservers if we can communicate npub to npub using nostr relays.

Understood. Idk if I'd call it a huge central using factor but it does need you to run a web server. Bolt12 will be a big deal when more widely used. But for now we have lnurl and it works.
