The Short Answer

The fractal amounts are still meaningful in many transactions. For example, if gasoline could only be sold for $4/gallon or $5/gallon would make a huge difference to the vendor and the consumer alike. Also, some industries live off those fractions. Credit cards, for example, charge the vendor a small fraction of the charge. Each charge isn't that much, but when multiplied by the millions of transactions every day, they add up.
