Logistics, supply, demand, price convergence, the Goldman roll, spot and position limits, there are SOOOO many factors much larger than a fuckin' banker dressed in a suit shorting gold.
That is true, and I agree with you in principle. It gets particularly messy, however, when
whatever combination of all these complex factors results in a wiping out of
the illusions of entire fortunes. And that begs the question, What were the causal factors that could ever have made them illusions in the first place? That, I think, is explicable and can be defined, without ever having to determine which combination had to occur and in what order for the illusion to be destroyed.
The problem, as I see it, is one of conflating causes and effects, and the tendency to focus on effects with no fundamental examination of the merits of the causes. It is very similar to inflation, which is looked upon as the absolutely meaningless "sustained increase in the general level of prices for goods and services" (focus on an effect with multiple causes), with no single word used to define "a dilutionary increase and subsequent debasement of the value of the money supply" (focus on a cause with multiple effects).
We are backwards in all of this, batting at myriad leaves and branches while leaving the roots unexamined. Those who see market manipulations (like JPM playing shorts against longs) as a fundamental problem
on its own, regardless of other causes, are answered with an
effects-centric "That's NOT the only reason prices change!" And while that is very true, it has nothing to do with examination of one core causal fundamental...in vacuo, on its own merits. Likewise, someone who sees prices of all commodities on the rise can point to "inflation of the money supply", but will be met with the argument that inflation (as defined only in terms of the effect - or "rising prices"), "...is NOT the only reason why prices can go up!" So what?
So yes, a banker dressed in a suit can short gold, even as he can create fictitious money, and these will not be the only causes, because there are indeed other, and even far more complex, dynamics involved. Focusing on the effects will NEVER produce any cut-and-dry answers, as the multiple causes will necessarily remain
forever moot. But what does that have to do with the fact that a banker dressed in a suit can do either of these things with impunity in the first place? To me that's like saying that the person shaving off parts of the outer hull of a ship is NOT the only thing that can cause a ship to sink. What do I care? How about we remove the ONE KNOWN destructive cause, assuming we could even focus on the cause, let alone agree that it is inherently destructive, before examining the effects?
An even better example: The coroner listed the official cause of Elvis' death as "cardiac arrhythmia". Well. How useful. And how many factors can cause that? Constipation, or intestinal blockage (death by inflation?) can cause that. But now we have to trace backward and ask what can cause such a blockage? Oh, lots of things, like eating tons of butter-fried cheese and peanut butter sandwiches - or, say, too many prescription medications. But let's focus on the arrhythmia, shall we? Pay no attention to each of the root causes behind the curtain, since any one or more of them in combination could have been responsible, but all likely played "some part".
