You don't understand inflation. Inflation is just adding to the currency supply. The 21m bitcoins will not be completely mined until around the year 2140. After that there will be no more inflation, ever. The value of 0.000001 BTC may be the equivalent of $1,000,000 in today's fiat terms, but that is not inflation. Actually it's deflation because every little bit will go further and as time goes on, supply will dwindle lower and lower driving the value up even further.
