Only when you also use that same base for everything else too. The decimal system works so well because it uses the same base as the number system we use (almost) everywhere. And actually I don't really think the lack of divisors is really a problem in base 10. It may be different if you're used to imperial units, but when using the decimal system you don't think in fractions all that much. You either use more places after the decimal point, or move to a smaller unit.
