  1. One major problem I can see with this. The Great Lakes may contain 21% if all the surface fresh water on Earth. But the Great Lakes themselves receive very little water in terms of their Drainage Basin. For the most part the southern shore line of the Great Lakes is a mere handful of miles or kilometers from the continental sub-divide with the Mississippi Drainage Basin. I'm currently sitting about 1 mile west of the Lake Michigan shoreline (SE Wisconsin). The sub-divide is around 4 miles west of me. The only US state that is entirely in the Great Lakes watershed is Michigan. Such a mega city would be relying heavily on what is in reality fossil water. If such a city where to be built perhaps a better location if water is the main concern is in Siberia surrounding Lake Baikal. Baikal contains more water than the Great Lakes combined. Granted winter weather might be a concern but in such a place I suspect the vast majority would never need to venture outside at all. Besides you could never have the entire population of Earth living there. You would need a certain percentage. Possibly less than 5% to provide all of the needed services. Food for one. The main attraction to such an idea would be the ability to return a lot of the Earth to a state of nature.

  2. It might be cheaper in the long run to start doing resource extraction in space.
