You have picked up on a problem satoshi and many others haven't solved. They, possibly being with little economics education, specifically designed a deflationary currency.
The funny part is watching Roger Ver and Charlie Lee push their own coins for utility use for daily payments in life. Charlie does not understand economics and Ver is simply a moron.
Anyway, bitcoin is still seeking price discovery of a larger magnitude and will continue to be volatile until that is resolved. My best guess (emphasis on guess) is that price discovery will be at much higher prices. Using your example, it will be a fraction of a bitcoin to make such purchases. At some point it will end and I would surmise government will step in, with blessing of certain corporations, for a national crypto. So maybe the conspiracy is true .
