Quote from PragmaticIdeals:
Unforunately, neither of the arguments in this thread are convincing.
Allowing privatized banks and central banks to manipulate the money supply at whim and create asset, price and credit bubbles (and then get bailed out after doing so) is clearly non-optimal.
Likewise, a gold standard is unfeasible for plenty of reasons:
1) Inefficient to allocate resources toward digging a rock out of the ground, which would then dilute the rocks of everyone else... Imagine if scientists could create gold in a lab.
2) Secular demand factors can drive the price of gold (i.e., how badly your wife wants that new necklace)
3) It is true that, over certain time horizons, market and structural inefficiencies can cause excess inflation or unemployment and these social welfare issues can be effectively mitigated through money supply manipulation.

All that being said, I think the best solution would consist of:
a) A fiat monetary system,
b) Disallowing banks to create credit out of thin air and fuel inflation/asset bubbles due to the natural conflict of interest between society's wellbeing and private profit maximization.
c) Allowing a government-supervised institution to manipulate the money supply within a narrow band (i.e., no more than +/- 2-3%)
