> Using self custodial LN privately is a much higher barrier to entry
Of the four UX hurdles I outline on this page (https://moneroleaks.xyz/), monero has all 4 of them and lightning only has 1, which is this: lightning users also commonly reuse the LN-equivalent of a monero address, namely, they commonly reuse the same pubkey in all of their invoices. Not to downplay that problem, but if you just go by the hurdles I mention on that page, lightning fixes 3 out of 4 of them and monero fixes none of them.
