i think this is inside job

All collateral should be send to a trusted escrow.

This is a strange discussion.  Must oil prices be a grand conspiracy that is only about some politics?
Is it impossible that there are new oil extraction methods that have become cheaper with technical advancements.
No one has heard of "fracking"?
(It is very controversial, possibly polluting ground water, but it produces oil where it was previously impossible.)

Commodities markets tend to over-react before they balance out.

Or maybe it is all just a few people playing global chess over some imagined strange excuses that make everything happen?
People look for complex excuses instead of looking at simple data.

The conspiracy is the market conspiring to find the clearing price.
Today Saudi announced it is reducing deliveries, the fracking is not economical at prices below the $60 barrels. 
At this price, new demand will arise and price will rise, then Saudi may increase delivery (or not).

Maybe many people assume that governments control everything always.  Does it feel helpless to live in such a world?

People were less shocked when prices soared for the last few years then when they fall.  They went up from war and rumors of war which are certainly political.  (Or a failure of politics)  But now it is a conspiracy when they come down?  Maybe there is a conspiracy for peace?
