I don't agree that 15000 could last forever : it would mean that economy has invented levitation law and many have pretended to do so since at least 200 years and each time economy and stock market has collapsed dramatically.
Just History about John Law:
http://cepa.newschool.edu/het/profiles/law.htm
John Law was a "reckless, and unbalanced, but most fascinating genius" as Alfred Marshall (1923: p.41) called him, with "the pleasant character mixture of swindler and prophet" as Karl Marx (1894: p.441) added. A Scottish economist, gambler, banker, murderer, royal advisor, exile, rake and adventurer, the remarkable John Law is renowned for more than his unique economic theories. His popular fame (infamy?) rests on two remarkable enterprises he conducted in Paris: the Banque Générale and the Mississippi Scheme. His economic fame rests on two major ideas: the scarcity theory of value and the real bills doctrine of money.
John Law's "Real Bills Doctrine" of money applied the "reflux principle" to the money supply. Money, Law argued, was credit and credit was determined by the "needs of trade". Consequently, the amount of money in existence is determined not by the imports of gold or trade balances (as the Mercantilists argued), but rather on the supply of credit in the economy. And money supply (in opposition to the Quantity Theory) is endogenous, determined by the "needs of trade".
Law's schemes were launched on the basis of this logic. Exiled in Europe because of a duel, Law ingratiated himself into the French court through patronage and friendship of the Regent, the Duke of Orleans. The state of French finances after Louis XIV's death in 1715 was so dismal that the Duke turned to Law for assistance. Law proposed the establishment of a state-chartered bank with the power to issue unbacked paper currency (see here for pictures of notes), the Banque Générale, which was established in 1716. Around the same time, Law also established the Mississippi Company, an enterprise designed to develop the then-French colony of Louisiana in North America.
Law's note-issuing bank was a spectacular success -- until it collapsed after a bank run in 1720, plunging France and Europe into a severe economic crisis, which had an important role in setting the stage for the later French Revolution.
