Lightning is in no way a replacement for Monero.
Lightning is not final settlement until it's on chain. Fully interactive. If you are not running a LN node 24/7 or trusting someone else to do it, rug potential is always there.
Most transactions route thru large centralized nodes.
But more importantly, it is not private, particularly reciever privacy sucks. Stop lying to people.
