Closing roads is a very effective way to advance the Wildlands Project.
In Mesa Verde County in Colorado, the Bureau of Land Management (under direction of the Federal Executive Branch) is closing over 600 miles of public roads in spite of strong push back from citizens, local government, and the strong possibility that the agency is not following either state or federal law.
In this article, the agency, after some initial efforts to get the locals to go along, simply forces the local governments to submit; leaving the only recourse for the local government expensive time-consuming litigation, and the citizens without critical roads. This is an example of how, as the federal government grows, the Feds can reduce the effectiveness of local government preventing it from protecting its rural citizens from federal abuse.
One more comment, remember road closures prevent economic activity by those who wish to harvest the resources on and under the ground. Every time Bambi wins, economic activity of our natural resources, coal, oil, oil shale, natural gas, minerals, trees, etc. is stifled. Without strong economic activity, we cannot be a prosperous nation.
