It consists of centralization this it'd likely produce a negative outcome
Discussion
All actions produce negative outcomes. The question is whether it produces more positive outcomes than negative.
This sort of centralization is fairly minor all things considered. It only affects about 40 million people. No conquest happens. No invasions necessary. No one dies as a result. Canadians and Greenlanders get richer.
American know-how creates efficiencies, especially at scale. Just ask the Saudis who couldn't get their oil out of the ground.
The plan will also make Elon Musk the first trillionaire as he will oversee the whole thing through the Department of Government Efficiency.
