When the US attempted to transition to the metric system, gas stations raised their prices per unit volume and the American consumer was convinced that the metric system was bad. I have family that think metric is bad because some fringe people thought there should be 10 hours in a day and 100 minutes in an hour, also something like 10 months a year, and the whole thing is bad because some awkward ideas were floated.

Here, it's a question of resolution, with a proven history that transitions screw the consumer, though maybe it won't be so. We're ok with arbitrary hundredths of a dollar, why were we not at thousandths? The American half cent disappeared a long time ago. You still need to include the cents in a tax bill that runs into the millions of dollars.

It's just an awkward stage in inflation. Eventually a US dollar will be worth what a Zimbabwean dollar was, and we won't have $100 bills anymore.
