there are definite advantages to transacting on an L2

after setting up your own LN node and opening your channels try sending 10M sats and tell me how it goes.

STN likes to pretend EVERYONE on LN is using proxys and trampoline routing (they aren't)

and EVERYONE on Monero is using light wallets that leak network info (they aren't)

you can have good privacy using either network.

But Moneros privacy guarantees are better known and battle tested.
