Your grasp of simple mathematics is terrible, if everything is divided by a it wouldn't make a damn difference in any value. sure, each coin would be worth times more, but it's the same relative value as they have now. The only real effect this would have is eliminating many peoples pennies. The only issue is MAX_TX, which as I've stated before, is easily remedied.
But if the value of 1 CENT is less than 1e-8 XPM then it can longer be traded (unless Cryptsy changes the way the CENT/XPM market works) making the coin completely worthless, whilst reducing the total number of CENT would at least allow the coin to continue being traded without changing its overall value.
