"This country was bounded to the West by a desert. One day a telescope built on one of the country's mountains revealed what looked like sea far away beyond the desert which would have to be crossed in order to discover if there was habitable land on the coast. So the politicians got together and established a government agency to send some people through the desert. They called it the National Agricultural Frontier Administration, NAFA for short, and charged it with a dramatic task to demonstrate the vigour of the nation: it would carry out a 'mission' to send people right through the desert to the West coast of the continent and bring them back safely, within a decade."
The whole analogy falls on the simple problem that space is just a lot more difficult than desert. You cannot just put a bunch of poor but adventurous people in a car and tell them there is free land on the moon. The moon is also a lot less hospitable than California.
