Truly useful work comes to two hours per week per person. Were productivity gains to continue as before yet be translated into time off, thanks to geometric progression, in ten years, it could be down to 6.5 hrs. Suppose libertarian reforms would lower the cost of public services by more than half, due to greater efficiency, plus eliminate corporate welfare. Both collecting and disbursing rent improve how we treat Earth. Collection motivates greater efficiency by resource consumers.
Disbursement lets people engage in less work, an activity that is resource-intensive.
Less consumption of sites and resources spins off fewer byproducts, e.g. pollution. And as revenue from a tax on pollution would fall, revenue from a fee pegged to land value would rise. Land value is a near perfect metric of the health of a society. As conditions improve, more people are drawn in, pushing up site values. There being fewer residents to share rent lets the CiDi hover around a comfortable level.
