You did not understand what dkbit98 meant at all? He is not referring to transaction fee. Even lightning network fee is either zero if you connect to another person's node directly or just of very low fee if it is not directly. What he meant is that the United States are going against noncustodial lightning network wallets. Although, Wallet of Satoshi is custodial but they went against it also likely because the Wallet of Satoshi does not require verification of identities which should be through KYC.
Unfortunately, with custodial Lightning channels that are opened by wallet providers to you, without your own money used for opening it, those are easily prey to KYC verification.
It is utterly moronic and stupid that we are now seeing verification required before people can even create a Bitcoin wallet, and yet here we are.
If you run your own Lightning node and open channels yourself then you don't get this kind of nuisance.
