Your concerns seem to be more geared towards dumping. This is only an issue in the real world when someone with a massive supply can continually dump to create a market dependence on them, but since anyone can be a supplier at any time in bitcoin this isnt an issue.
Are we talking about the same bitcoin where greater than 50% of the currency to ever be created is in the hands of <100k people? Where 20% of it is probably in the hands of a few dozen? I don't know how you can possibly make the argument that bitcoin mining is somehow a solution to demand when it is, by design, a choke point of the currency. My concerns are not "more geared towards dumping", they are geared towards providing a stable currency base that is difficult to manipulate by those who mine, those who have coins, or anyone else. This is
without resorting to some kind of centralized solution or being tied to hard formulas that will not be able to adapt to reality.
