I think we still need to make it a little simpler for merchants and users to trade bitcoin. Part of that is UI, part of that is lightning, part of that is L1 work. No sense telling people to spend or receive bitcoin as income when we are relying on sketchy and difficult things like static channel backups and SD card wear out, non custodial lightning.
