That is the money multiplier.
The second implies that the Fed creates money for any reason and then injects it into the system through various means. The first implies that someone has to borrow money from a private bank, with the Fed creating money to fulfill the loan request.
The implication is that removal of the Fed becomes irrelevant as most money is essentially created by private banks as they extend loans. Without the Fed, private banks will lobby and create a new central bank that will print fiat currency to meet loan requests.
Keep in mind that in order to earn from savings, banks need to lend them to someone who has to pay back the loan plus interest. In order to pay interest, the borrower has to either deposit that money in another bank that offers higher interest or invest it in a business that will produce and sell. The pressure to produce and sell more obviously increases with higher interest rates.
The same goes for the rest of money supply, which increases because of fractional reserve banking.
That’s why the money multiplier exists. Recall that it refers to money supply increasing given an initial amount injected into the system by a central bank. That’s why M2 is a lot higher than the money base.
For the money multiplier not to exist, almost all of M2 will have to involve money injected into the system by the Fed.
Businesses and banks want to avoid inflation as that leads to lower sales.

Actually, it works both ways. That is, what you save is gained by selling to another who will consume what he bought. If he doesn’t buy, then you have nothing to save.
Unlikely, as financial elite existed long before central banks were formed.
