While there is a general acceptance of the role of private property for social order and economic prosperity, the challenges to private property have not ended. The eminent domain issue is one threat; another comes from environmentalist groups such as the Foundation for Deep Ecology and others who see humans as a drain on the earth and nature. Some environmentalists advocate the consolidation of land to be put under federal control and promote stringent land usage restrictions that would prevent a landowner using his property fruitfully.
Their argument is nothing new: individuals left to themselves will not be as effective as central planners in decided the best way to allocate and protect resources, etc. etc—they are merely variants of the Marxian arguments used by economic central planners.
