Existing Helium-3 market could finance lunar elevator today

Markets consider upside pressures and downside pressures.
Helium-3 is a very unusual commodity, in that it is completely synthetic, and the Helium-3 traded has not been naturally occurring in nature.
We have been feeding off of the nuclear warhead stockpile which has been the source of all the He3 in the world... that warhead stockpile is now mostly gone, so the rate at which we can replenish the He3 stockpile has dropped off a cliff
We are now left with a known finite stockpile of He3 which is shrinking at a known rate.
Unlike most commodities, we know exactly how big the He3 stockpile is, and we can track how it is being consumed.
The stockpile is now down to about 50,000 liters, and the US DOE is presently releasing it at about 14,000 liters per year, and replenishing it with 8,000 liters per year.
Since natural demand has been demonstrated at 80,000 liters per year (2008), DOE is implementing a form of strict rationing, to try and eke out the He3 stockpile as long as possible.
There is a shortfall of 80,000 minus 14,000 liters = 66,000 liters of pent up demand, or to put it another way, the existing supply of He3 can only satisfy 17.5% of world demand.
There is no terrestrial solution to the He3 supply side, so for once the Moon has a real shot at being a solution to a real terrestrial economic problem.
There is a good window of opportunity to develop a lunar He3 mining solution, the window will likely last decades, so force once we have plenty of time and plenty of money. It is an unprecedented market opportunity for lunar development.
