<p>Most of the above would work in other monetary systems as well with some caveats. The main justification for fiat money is that it wastes less resources than comparable systems such as commodity money or gold standard.

<p>Ultimately any money is based on trust that someone else will accept your money and this trust can be created via government requiring all taxes be paid in its currency (you always know the money will be useful for something so you accept it).

(Asked by: username_0 on 2021-01-28)

some people suggest that the government prints money to pay its bills and that the increased amount of money in circulation lessens the value of $1. i hope to get an explanation of why both assertions are false and suggest the following:

the Federal Reserve Bank (Fed) inserts money into the economy thru loans. at least two questions arise

1. presumably if all loans were paid back, there would be no money in circulation. but corporations borrow money to build products and others borrow money to buy those products, hence a never ending cycle. so Fed balance sheet every expected to
   be zero (i.e. no outstanding loans)? and what happens to the money in circulation from defaulted loans?
2. the "value" of money is presumably based on supply and demand. this presumably counters the idea that the more money in circulation reduces its value because as the population and economy grow, there is a greater need for money, maintaining its value. when an economy shrinks, the fed makes fewer loans and as loans are paid back, the amount of money in circulation is reduced. further, much more money is needed in circulation today than in colonial times (as an example) simply because there is a greater population and need for money (or the economy has grown).

are these concepts correct and do they explain/justify fiat money? what concepts are missing from a more comprehensive understanding?
