The counter to this point is that if (through monetary mismanagement) the amount of dollars exponentially rises, the value of those dollers drop. Fiat isn't backed by a hard asset; it can be arbitrarily increased/decreased in value through organisations and unelected officials.

The original QE decision by the fed was taken during a meeting that has meeting notes that can be downloaded. I highly advise you to do so if you are under the illusion that the decision was made by highly competent experts basing their decisions on hard data and well-made, objective models.
