How will they control ALL the lightning nodes, anyone can start a node.
I already answered that. Lightning nodes are NOT invisible. Nor are football stadium sized mining facilities. If you think a professional money laundering enterprise - that's what freelance lightning nodes will be known by to the govt - are somehow immune to govt regulation when they can easily come knock on your door, you're out of your mind:
Anything that has an easily identifiable physical or digital surface attack vector will be enveloped by the current system. Claiming you're going to run a wildcat Lightning node is like claiming you're going to be some type freelance illegal porn distributor and the FBI is not going to kick in your door.
