Instead of continuing to argue on specific points, I will say I think you are grossly misunderstanding the level of deflation we are talking about.
There is no sharp boundary between a +0.1% inflation rate and a -0.1% deflation rate where suddenly all hell breaks loose. The importance of changes (bad or good) vary gradually along the line. And if the Bitcoin economy stabilizes to representing a fixed fraction of the worldwide economy (be it 1 or 10 or 100%) then the rate of deflation Bitcoin will endure would be equal to the rate of growth of the economy. So we are talking about 1-4% only (average OECD world GDP growth for last few years).
