There's no cliff (at least for this to be the third, or even second, derivative with regard to.) Its not like there is a magic bad nominal price level.
Right, the cliff is when people lose confidence in the dollar, which probably has a lot to do with the inflation rate, changes in the inflation rate, and the duration over which we've seen what sort of behavior (... and probably a lot of other things) but not much to do with the actual price level itself.
If we average 2%yoy every single decade for the next 300 years, people will probably have a lot of trust in the dollar in the decade following. If we hit that same price level tomorrow, people will rightly flip. $1700 milk either way, but in one case we'd expect $1700 milk the following day and in the other we'd expect the dollar to plummet further from the shock of it.
