The fed was created by an act of Congress. It could be uncreated just as easily.
No, it could not.
Huh? What are you talking about? Congress can overturn any law it has ever passed with another law. That's how the Constitution works. I really don't see why this is particularly controversial...
Now, you can argue that it would be
very very bad to get rid of the Fed, but that is a very different argument than saying it's impossible because it secretly controls people's brains.
What you seem to be up against is that he Fed is actually a
good and useful thing that enables our modern economy. Saying this is some kind of tyranny is like saying that electricity is tyranny since modern civilization can't live without that either.
And the Fed's independence--which, again, could be revoked with a simple act of Congress--has remained that way out of fear that some politician e.g. Trump would just order the Fed to do something dangerous because it helps him politically in the short term, not a secret room with jews.
The people who "own the Fed" are the ~335 million Americans who control Congress (or, okay, the ~140M who actually
vote). The same people who own our nuclear weapons and own Yellowstone Park, for instance.
