If successful, it would quickly lead to doubling the world population to 18 billion.
I remember in the late 60s when the Interstate 270 circumferential road opened around St. Louis. The officials claimed that traffic jambs were cured for forty years. Of course, the developers quickly built out all the newly accessible land with mammoth subdivisions and within a couple years things were as bad as ever.
The population always has a tendency to expand to consume available resources.
If you build something in the middle of nowhere, it becomes the edge of somewhere.
Universal truth. Like rearranging your garage to make space, somehow it fills itself - quickly.
