How big a problem is it that bitcoins are finite ? The minimum unit of a bitcoin today is a satoshi, there can ever be max about 2200000000000000 satoshi. Is 2200000000000000 units of currency going to be enough to run a global economy ?

Finite being no-inflation. There is actually no technical limitation from stopping the subdivision of bitcoins.
