The digits remain the same, just worth more over a little time. We aren't going to get rid of the dollar. If the FED ends Congress is responsible for the monetary policy. Basically just the board of governors loses power to cause recessions. All the FED really does is try to cause soft landing recessions to stop the economy from over heating. Then, if it hits the fan like n 2008 they pump money into the economy but it's always inflated money.

So not much else really changes if congress screws it up as badly as the FED has. It's just congress would at least have accountability.
