it is impossible for a large number of people to run their own nodes. not just difficult, actually impossible. almost everyone on lightning is using an IOU system to borrow channels being operated by a business. they are not using their own nodes. lightning was invented to reintroduce banking into bitcoin. it is the reason why these companies exist. if lightning works, why do these companies need to exist?

It is kind of parasitic in that way too since transactions happening on lightning don't pay miners transaction fees to secure the blockchain. If most transactions are supposed to happen on lightning in the future, and block subsidy is going away, who is going to pay miners? Lightning works for now, but a Drivechain future seems more symbiotic and sustainable.
