During the 1840's to 1860's we created billions of dollars out of thin air by mining gold from the ground in California. Fiat currency saves us the digging.
Money is not a static "thing" that definitely exists. Markets need liquidity. QE has provided that liquidity as the vast majority of capital in our society has become locked up by the top 1%. If anything, they could increase the flow of QE because of how low inflation is right now.
(Also, they're arguing against QE, not the entire concept of fiat money.)
