This reminds me of a Soviet joke:
Q. What is the most valuable real estate in the USSR?
A. It's the state border. If you owned just a meter of it you could have made billions by letting people out.
I rephrased the one I've heard due to obscure cultural references which even Russians might not understand if they are not old enough. The original is "Кооператив "СВОБОДА" возьмет в аренду 1м государственной границы"
