The market and money in particular are complex systems, and as a general rule I would never try to mess, tweak such systems because there are way more changes that brake them than beneficial changes. So I can understand a general feeling against any weird ideas of messing with money or money supply and apply that to the general society. (John Gal make an excellent case for this line of thought in Systemantics)

As I understand it so far, money works both as an abstraction of the goods and services in the economy (decentralized mechanism to distribute right to consumtion of the stock of goods and services) and a communication layer for decentralized knowledge. Messing with it will mess both of that functions but the most stable "fideling" will be the one that hide better under the rug the casual relationship between cause and bad effects.

Is interesting the example of gift cards, is something you can "print" out of thin air but I believe it works as fractional reserve, the moment you have a sort of bunk run it will be obvious that you gave more gift cards than what you actually have available in goods and services. Isn't exactly that what the FED does with its balance sheet? and even worst, they fiddle with the interest rate which is the same as fixing a price and will cause underproduction or overproduction of the good, in this case society real savings
