I mean: if a government backs a money system, it can take some politic moves to safeguard it and its users. For good and bad, government is somewhat free to regulate its distribution throug many mechanism: generating more or less, charging with taxes some transactions, etc. Some of these moves have not much consensus, like creating too much bills, which may generate inflation, but some others tends to protect small player from the power of the big ones, like taxes for the most riches, etc.
The problem is there is no backing of a monetary system, it is only about trust. If it go really bad, no one help you as there is no backing of monetary system, you will have just useless papers.
