I would agree that no one uses it - but not out of convenience. It is an adoption problem, no one accepts lightning payments because no one has lightning balance. If you download a modern, non-custodial wallet such as Phoenix or Wallet of Satoshi, it is easier than paypal or my online banking website. It sure as hell is easier than opening any online bank account (Wise, Revolut etc.) as there is no kyc.
Regarding anonimity when exchanging, yes. But you can make the same point about cash. You are identified when withdrawing, and identified when depositing. You cannot be identified when cash changes owners, and the same holds true for lightning payments. So if anonimity is the same, lightning is still to be considered superior as it works also for online payments while cash is bound to physical means of payments.
