Money, organically, is not a thing you can play with in state craft.
Money is better explained if you realize that every economic transaction is barter, and money is something that has universal demand, and therefore can be bartered for anything.
Simplify the economy down to apples, milk, and eggs. Everyone is either an apple orchard owner, or a chicken farmer. Sometimes, the apple orchard owner needs eggs, and sometimes the chicken farmer needs apples. But they both always want milk, which is rare and highly desired for whatever reason in this world.
Sometimes they can directly barter for each others apples and eggs, but sometimes they can't. But they can always barter for milk.
Well now, milk has become money, and it's much easier to simply establish a price per gallon of milk, and always use milk to trade. You can't just artificially make "milk notes", not backed by actually milk, and print more milk notes to stimulate the economy. These people want milk, what good is a piece of paper that claims to be milk? It's like transmilk, paper that pretends to be milk by writing milk on itself. How Jewish can you get?
Theoretically, you can make milk notes which are easier to haul around, and let anyone exchange their milk notes in for real milk at their leisure. But then if you arbitrarily inflate the milk notes, at some point there will be a run on milk.
So if the state is going to create currency, it should be backed by what the universal barter item is in their culture. And it should be issued by the amount of said barter item held by the state, which it shall issue in place of said notes if so desired. And vice versa. So for example, a gallon of milk is always worth a one gallon milk note, regardless of how many apples a gallon of milk is worth.
Now of course milk sucks as money, because it spoils. Traditionally we have used gold, but it could be other things as well. Now the "trade value" of these notes can inflate or deflate based on the supply of gold. Traditionally there is a natural stabilizing force. The population tends to increase, and we tend to mine more and more gold. Sometimes the population decreases, but sometimes gold is lost or practically destroyed.
Perhaps there is something better than gold, but the universal barter item should be what is in question. Not whether or not it's good to arbitrarily inflate the notes that represent that item.
That's called lying, and theft. Which doesn't work well if you are trying to establish a stable economy.
