in a system when you generate currency from nothing, this is true. But if you use currency as an actual IOUs, you would need to generate value to generate currency, and thus, if you were to hoard currency, you are providing value to the economy for nothing in return, which is a good thing. If it were possible to credit processing power dedicated to systems like folding@home or BOINC than I imagine that would be an ideal cryptocoin contender.
