Labor is the active force, and land is the passive force. Production cannot happen without both. As for everyone being rentiers, I'm not sure I see the problem. Everyone being rentiers ensures a minimum standard of living, allowing us all to share in the progress of civilization. But really, land value taxation itself raises the "margin of production" even without any kind of redistribution. The mention of trickle-down seems like a non sequitur.
