Since the money-market system is fundamentally based on debt structures, circumventing any kind of crash will be tantamount to preventing any kind of overvalued market. In other words, no amount of mathematical juggling will alter the underlying sine qua non of the (global) financial market. Frankly, any newly put forward mechanism suggested should be subjected to serious analysis and scepticism if the true goal is to avoid a crash. Looking over the history of the financial markets, however, given anyone who works within the system, I would doubt that they would care to envision, let alone implement, any kind of method that would not have a necessary relationship to their securing their bottom line.
