Granting the assumption of monotonically increasing inflation at a wild rate, this is still only true ceteris paribus. I can't imagine inflation that would make a small coffee shop chain into 50m/year revenue (customer floor requirement notwithstanding) would happen in a vacuum.

What he means is regulatory inflation, not the monetary one. A few years later, the customer threshold would be amended to a few thousands, ten years later, the thresholds would be abolished.
