We already have hosted channels, 0-conf channels, cashu etc There are many ways to onboard "zero sats" noobs.

Do you know that I can open a 0-conf channel with your node and in an instant I can send/receive sats without even leaving a trace onchain and never close that channel?

Zeus also have a nice onboarding strategy: with the graduating wallet 0-sats user start with cashu, stacking slowly. When the balance is high enough the user can open a 0-conf channel with the LSP or any other node and have a proper LN channel. But very few people are studying all these aspects and use cases.

Few years ago I did an experiment with a school. Onboardingn an entire school kids and teachers starting from zero sats. I used a LNbits, a bunch of empty wallets and opening 0-conf channels. In few days they start having each some sats, without knowledge, without buying any sats from exchanges, only from an ad-hoc bitcoin circular economy. And nobody says that LN is hard to use !
