You've derailed from the topic but did not explain how zero money is introduced into the economy.
...Of course the UST is the USG, since USG is umbrella organization of all its departments, but UST doesn't spend it. Anyways, this is besides the point - you're trying to get me to talk about this instead of what you're wrong about.
The money UST raises goes back into the economy when it is spent by the USG. It doesn't get taken out of the system, and you're left with a net positive increase in monetary base, and thus inflation, which is what the Federal Reserve is trying to produce.
This rhetorical question you wrote several pages up is ridiculous. Since increasing money in the economy to provide increased spending to make prices higher is entirely the point of the QE programs; The Fed is doing this so its inflation target is reached.
