Let's a little more cllear and honest.
It isn't really a private corporation, it is a semi public entity that can be shut down at any time, and also whichust give all profits back to the US Treasury.
The fed presidents and chair are all publicly nominated and confirmed with term limits.
Congress can audit anytime they want, they can kill it, change it, restrict it.
They choose not to.
You do not need fiat or the fed to run a deficit and rack up debt. That is completely untrue and counter to history.
Prior to 1913, the US government has plenty of debts. It is easier with the fed and fiat, absolutely. But countries have always borrowed and debased 'sound money'.
Everything in life only has value because Use a belief it does collectively.
The dollar, gold, oil, Bitcoin.
There is no such thing as intrinsic value. Bitcoin has value because we say it does.
