As if transparency matters for them! They need those cantillions.

I see no problem in people using fractional reserve lightning. When they want to buy something in real life (not fractional reserved) they would have to pay on chain bitcoin, so their financial games would only work internally between fractional reserve lightning channels.

Once they try to settle onchain the will need 10times of the fractional reserve lightning "Bitcoin" .

So basically the playfield is levelled for everyone and cantilliinaires only have am advantage when they only deal with other fractional reserved entities.

I hope you understand what I mean, as I am not a native english speaker.
