The Federal Reserve is also intimately bound up in fractionally reserved expansion of the paper currency, so it is reasonable to assume that they might use the same basic technique with gold. And that, in fact, is the historical origin of banking, in the modern, leveraged sense: gold assayers began loaning out gold on a fractionally reserved basis, allowing them to collect interest beyond their core assets. Worked great until people ran on them.
So I assert that it is less irrational to believe that there is a possibility that central banks engage in manipulation of gold prices than it is to believe that there is a dinosaur living in the subway under manhattan.
YMMV.
Also, to believe this you have to postulate that:
1) Employees of the Fed are personally concerned about gold destroying the dollar.
2) They are willing to do something illegal (or at least unauthorized) to protect the dollar.
3) So they came up with a complicated, elaborate plan to manipulate the price of gold down that perfectly plays into the narrative of gold bugs (note the nefarious fractional reserve lending).
It's not impossible!
2) People involved in the banking system, by definition, are willing to fractionally reserve something
3) Nothing particularly complicated, same fence that fractionally reserved frauds have been running for a thousand years.

To be clear I'm not saying this is what happened, just that there doesn't have to be an ongoing conspiracy among hundreds of people and institutions for the gold to be gone and nobody wanting to say anything.
I'm not sure I understand you fully. What is this portion of your comment analogous to?
But seriously, there are lots of things that are hard to prove wrong, but that's hardly a good reason to believe them. In your case, what motive would the Fed have? Has an employee of the Fed (or any other central bank) ever blown the whistle on this massive international conspiracy? If there's no good reason to think something, there really isn't much good reason to spend time proving it wrong.
