my opinion: LN / echash and maybe Liquid wallet integrated into nostr clients (in a usable way, not NWC) would allow people to have both in their pocket, and zapping should be as easy as paying someone with WoS. That's however, not the case, not at all... as we're even struggling to have a NIP05 verification process that is doable for 30% of the people. let alone zapping. (fun part: I can't zap from within my mobile nostr client, whatever I try, it all fails)
