Because it's irrelevant?
No man... it's not irrelevant... it's the basis of the entire experiment. If it falls to pennies or lower... it's game over for all of us... We have two choices at this time.
1 - Exponentially increase the market size, get VC money into bitcoin companies, widen the adoption rate of bitcoins to exceed $1.5 million a month of investment, and trading of BTC. (that's the figure that would have kept prices stable at $6 per BTC)
2 - slow down the rate of printing.
Pick one or both... it's not like any of us have any other options if we want BTC to survive. Facts are facts man... and the fact is that BTC will hit the point of no return if one or both of the above or not done. There really are no other options as it MUST be one or the two... the option 3 is do nothing and watch it go to the wrong side of critical mass.
The rate of printing coins is one of those constants that, if tampered with, would undermine confidence in the entire protocol. Very bad idea to even think of tinkering with such a thing. The market price is the variable, and the market decides what it will do.
And suppose the price started rising rapidly, would it then make sense to increase the speed of coin printing? No.
The market price of Bitcoin is what it is. We ought not try to "tinker" with the rules just to hold it higher than the market otherwise prefers.
To anyone who believes in Bitcoin, a falling price is a godsend opportunity to acquire more. It certainly does not indicate that the core constants of the protocol ought to be messed with.
