Yes, you're correct. Lightning obsoletes monero.
Discussion
In what way?
Lightning:
❌much effort and maintenance to attain what is already inferior privacy vs monero
❌nodes w/ most liquidity = points of centralization
❌not final settlement
❌requires a 24/7 active node to not be rugged
❌hot wallet
❌lacks L1 security guaruntees
...and right now 90% of lightning users are using it with custodial solutions
oh forgot one...
❌possible forced channel closes when tx fees are high on L1. Ouch.
