The biggest difference between bond issuers is that greater trust leads to lower interest rates and thus cheaper borrowing. For example, the US government sells bonds with lower interest rates than any company - buyers demand more return for a corporate bond, because a corporation is more likely to go bust.
For simplification, there are two kid of moneys, the 'government money' and the 'lending money' (my terminology).
Government money would be: cash and reserves.
Reserves come from two sources (both are the government) the Central Bank and the treasure. So, when the treasure spend in the economy is creating government money. Also, when the central bank 'give' reserves to the private banks is creating money. When the govenrment tax is destroying money and when the Central Bank retire reserves of the system is destroying money.
The 'lending money' is created by the private banks when lending, but it disappears when the money is payed back. This is a different kind of money, a less 'real' money if you want.
