Lightning scales very well.
Except when you need to get new liquidity.
I tried opening incoming liquidity channel with phoenix wallet and it asked me to pay equivalent of 80USD for 1000USD of incoming liquidity.
This is unreliable because during congestion users can't open new channels. Theres simply not enough base layer capacity to address high traffic scenario.

True, but there's no tie between your identity and your address. That should be good enough for most cases
