> If I deposit $1,000 into my local bank, and they turn around and lend $900 of that back out, that creates money.

While you are right about fractional reserve creating money, this example is a common misconception. When you deposit $1000, the bank assumes a reserve of $1000 and lends out $9000. This, is assuming the bank has enough reserves on hand. And reserves for the bank is either central bank money (given by fed) or treasury bonds (bought from your $1000 deposit) or MBS (bought from your deposit).
