I wonder, could you manufacture that? It seems to be happening in e.g. the middle east where they conjure up a city in the middle of the desert and just... create demand for a city there.
Take SF, which has a lot of tech jobs that aren't tied to any geographical location. Build a new city, offices, a university, loads of housing and make that the tech / internet capital of the world.
Could you manufacture that for like a trillion dollars? Maybe, but there are better things to spend a trillion dollars on. That's the entire Medicare budget.
Could you manufacture that for like a billion dollars? No.
