Yes but maybe I miss something. I'll answer point-by-point if you want.

- 1) openness: LN over nothing can interop with normal LN, and LN over Liquid can do the same. No difference here.
- 2) fragility: high fees are not that important over L2 such as Liquid, and flooding an L2 is unlikely. Not sure about griefing attacks.
- 3) prepayments: I wonder if Cashu can fix this problem for normal LN
- 4) hot wallet: wait what? why there's no signatures happening in Rumble? How would parties authenticate each other?
- 5) custodianship: LN nodes are not custodians, who says they are?
- 6) fun: no comment

Also implemented in: hawala, interbank network and whatever this is: https://trustlines.network/

But why settle on nothing when you can settle on something? I'd like to see Lightning over Liquid, for example.
