Yes, I have. It is too expensive for most people to get.

Also "will adapt" isn't viable sollution. We need something rn so we can start using it whenever a government starts to act bad. Not start thinking a sollutions after the internet has been stopped.

Another problem I am thinking of is extreamly high fees. Since I don't think how lightning can work over satelite or whatever the tech used is. There won't be as many miners and too many transactions.
