Its a layer, it has different persumptions and provides different features. It is a final settlement, given the assumptions of lightning the bitcoin in the channel is owned by whoever has it in their balance, theres no need for a layer 1 transaction to take custody of it because its not in your counterparties vault, its in a channel with an enforceable claim; layer 1 transactions will be relegated to shifting liquidity, not final settlement. Maybe that doesnt provide the space for 8 billion lightning nodes, which most people are never going to run anyways, but it does provide room for millions/tens of millions of lightning nodes. I know you want a perfect digital bearer asset that can be sent like a text message without counterparty risk or scaling issues, with perfect security and privacy, that is absolutely scarce like bitcoin with google level UI, and I know you want it yesterday, but 1. Monero provide that either and never will, and 2. this is a problem thats plagued humanity for millenia and we are going about as fast as we can, so strap in.
