Will any "Freedom Cities" be built in the United States before 2040?

Donald Trump, aiming for a 2024 presidential bid, proposed building up to 10 "freedom cities" on federal land, featuring futuristic concepts like flying cars.

Trump says he would host a contest for the public to design and then build “Freedom Cities” on a small portion of federal land to “reopen the frontier, reignite American imagination, and give hundreds of thousands of young people and other people, all hardworking families, a new shot at home ownership and in fact, the American Dream.”

This plan, part of his vision to lead America in air mobility and away from China, lacks detailed funding strategies.
