Other nation founding groups seem to have similar lifecycles, where an initial burst of enthusiasm gives way to a growing realization that it will be impossible, or at least a huge amount of work, to turn vision into reality. Basically, the amount of capital (billions) required to build these places is simply too high to be obtainable. It is awfully hard to make a business case for something new, huge, and expensive. This is why we've chosen an approach which reduces the required capital by several orders of magnitude.
