You're conflating anonymity (hiding identity) with privacy (hiding contents of a transaction)

One is wearing a ski mask while having a public conversation. The other is knowing who is in a room, but not being able to hear their conversation.

No privacy makes it easier to weaken your anonymity over time. You need both.

Privacy that Lightning vs Monero offers is nuanced, but I doubt you'll admit that.

For example every node on your Lightning route knows amounts passing through them. Monero nodes do not.

On the other hand Lightning offers better receiver privacy if used correctly. Most lightning users on Wallet of Satoshi and Strike have zero privacy from them. They know your balances and how much you receive/send. Similar to a traditional bank.

Yep there are trade-offs to everything it just depends on your goals and what you want.
