What I said about the Fed carrying out the government's spending orders is true, but what you said here doesn't follow from that.
What you said isn't true. It only appears like it because historically the fed hasn't been willing to make waves. You are basing your argument on a perception. If we were to do what you want to do, and at some point the fed decides not to support the effort, the US Treasury would be issuing more bonds than the Federal Reserve is issuing Federal Reserve Notes to buy them. This would cause bond rates to rise much like what happens in Europe when Euro countries issue bonds without the support of the ECB.
What effort are you referring to that the Fed might not support? Congressional spending?
I'm basing my argument not only on perception, but also on the Fed's job - it is our central bank. What else are they going to do, but follow the government? Lay it out, and give me some hypothetical scenario that you think would illustrate your point.
I'm not arguing that there aren't checks and balances, or that the Fed is powerless. No matter what the laws say, there isn't a bunch of case law to fall back on at this level. Yellen could certainly dig in her heels and refuse to do this or that - her exact powers and limitations are not as well-defined as they could be. But what
is written doesn't favor the Fed - there is clear language in the FR Act that gives Treasury the edge in disputes. If the Fed strangely decides to go maverick, I'm sure it would get wrangled out pretty quickly, either politically or in a quick court ruling. And my guess is, the Fed is going to lose that battle to the executive/Treasury either way.
But this is all getting far more theoretical, and uniquely American (process-wise), than I intended. The point was, the govt. can make money without cost. Govt. bonds themselves are adequate collateral. So it's really all just accounting now. The govt. creates bonds out of thin air, and more dollars are created. The govt. could (probably) mint a trillion-dollar coin, and $1 trillion new dollars are created. In the future, maybe the govt. changes a few laws so they can issue dollars directly, then does so. It's all the same thing in the end, because all of the hoops they make themselves jump through are self-imposed, and they really don't change the final outcome anyway. Governments sovereign in their own currency can issue that currency in any way they please. I don't know the exact details of how the Japanese create yen, or how Canadians or Australians create dollars, etc., but I do know that, like all fiat currency regimes, you can distill it down to the government creating currency at no cost. And none of those sovereign bonds that only promise more soft currency are true debt.
