The integerial divisibility of the inferial system may have made sense IN ITS TIME.

But, as the world evolves, there is no need to keep using an awkward, antiquated system just because it's traditional. It's conceivable that the old English money system once made sense but even the English eventually realized that a decimal system made more sense and fewer mistakes and thus, despite protests from the traditionalists, changed over. If the traditionalists were to have their way, we would still be using Roman numerals and Egyptian fractions.
