Why not just buy Belgium? Better chocolate, though it does come with Belgians. Ugh.
Belgium would be pretty expensive. Plus, I don't think it would be a good site for my African Game Preserve/Neolithic Animal/Battle Re-enactment Park.
Belgium is about 30,500 square kilometers, which comes out to about 7,533,500 acres. How much do you think that would cost to buy out on the Great Plains? No more than $1000/acre, I imagine. Probably less. Say, $7 Billion. Warren Buffet or Bill Gates could afford that, easy.
