Not even as difficult as that. As the prices rise with a regular periodicity, people stock up more goods with expectation that in future their money will buy them less. Which causes more price increases and corresponding increase in stocking.

Obviously 6% won't do that but at higher levels its the complex dynamics driving inflation than good old supply demand balance. And don't think that exports will solve hyper inflation because at that point other countries will also expect devaluation in currency which becomes a self fulfilling prophecy. Again not applicable to dollar and USA for the moment but at higher inflation levels anything is possible.
