Bitcoin allows us to send meaningful amounts of money to each other using a set of simple software tools and the internet. That's it. No complex node setups or trusting third-parties with funds and infrastructure... It is purely peer to peer.
Lightning has not accomplished this and at its best requires so much compromise to work for most people that even if it technically operates on bitcoin, no one interacts with actual bitcoin in the end. You're better off using dollars or any other kind of fiat. Or just the main chain if you must.
It's a shame how much the apologist narrative around lightning has taken hold because it obscures the fact that it is less useful than regular money in so many ways. Many lightning advocates suffer from a sunk cost fallacy. It's time to move on.
