It'll make it cheaper though. And those who still can't afford the main chain can use lightning. If I'm sending 10m 10k isn't a big deal. I just closed a 1.1m usd real estate sale in a developing market. See my note. I had to arrange 4 bodyguards, 3 cars, decoy duffel bags etc. As the buyer wanted to pay a large portion I'm cash.

not asking about lightning here, that's another topic unrelated to what im trying to figure out here (ie. effect on selfcustody)
