this seems like a reasonable view, but it seems like a "Bitcoin isn't going to be used by a large number of people anyway" view.
and as long as a large number of people aren't using Bitcoin anyway, those people can run their own nodes
what exactly do you think the positive trade-offs are, of using something like Spark as opposed to trusting a L1 node I mean?
I'd suggest that people are using lightning because zero conf transactions were taken out behind the woodshed and shot.
