So government income will depend on making land more attractive.

Ground rent makes everyone richer. Richer people like their own part of the world to be beautiful and healthy. Ground rent makes your life easier, so you can spend more time on things that matter.

Ground rent makes natural resources more expensive, but work is untaxed, so is cheaper. So there will be a strong move toward renewable energy and recycling.

Faster economic growth brings more scientific advances.

Ground rent makes it easier to measure real costs. Anything that poisons the land will not be tolerated.*

*(Because ground rent makes governments compete for workers.)
