I don’t agree. Orlando was nothing. Raleigh research triangle park was nothing. Silicon Valley was nothing until they were. Each of them were built from a single seed project: Disney, State grant of free land and two roads being built, NASA facility respectively.
We could also recognize that at certain levels of development single family residences are no longer viable. The government should use eminent domain to take entire blocks back for redevelopment vertically. They should be required to give the home owners triple the value of The property they are taking in the form of replacement square footage or a property in the new development and one or more properties elsewhere. Imagine ing each nimby stood to have a windfall in the form of multiple properties they could rent or sell in exchange for giving up their property. There would be a lot less resistance. Not no resistance but a lot less.
Build the infrastructure, plan the city grid like we used to, incentivize employers to move headquarters there, build new factories, create special economic zones. There are tons of options.
We could increase supply and demand by having a “grow to 1 billion Americans” project. We would create a path to citizenship for people with a requirement that they help build and/or finance the build of homes store fronts etc. create a targeted immigration plan so the new metro is comprised of a broad range of culture, ages, income levels and skills so cultural mixing occurs and assimilation into the shared American experience is facilitated. Make the new metros operate on lower minimum wage, grant 5 year tax abatement for individuals, give the land away for free. Then once the city is established in 20 years do the same thing.
