Again the purpose isn't to stop the correct or incorrect revaluation of the currency, it is simply in place to increase the quality of life for the majority of users by attempting to provide some form of logical or at least mathematical attempts at price stabilization without arbitrarily deciding the value of the currency. Furthermore any increase in the total amount of emu will be split up as 10% for the buffer and 90% as interest and payment for processing transactions.
Quality of life will not be improved if the price stabilisation is broken. Furthermore, you cannot 'arbitrarily' decide the value of the currency in a free market.
The market maker model of price stabilisation works by creating huge buy/sell walls around your currency valuation price; the idea being that, since the system is the majority holder on both sides of the market, it would be impossible for anyone to eat through those walls. However, you can see where this starts to break down if the system is not the majority holder, or starts losing it's majority over time.
Let's wait for the complete details in this before we pointlessly debate.
