This is a horrible idea. Just think of what the final number of BTC will then be: 21 trillion. Not one person can wrap his mind around it,
It's not like people will talk a lot about the total number of Bitcoins (do you often here people discussing how big the US monetary base is?). What's interesting is how many Bitcoins I have, how many Bitcoins you have, how many Bitcoins that computer costs etc. Those numbers will not be trillions.
