No, that's only one of the issues but it's certainly an important one.
The real issue, if you insist on characterizing it as 'just one' is government interference driven by your favorite 'interest group' from environmentalists to 'not in my backyard' 0-risk advocates distorting market factors and just about everything else. Not that those concerns are invalid but the single minded, to hell with everything else, fanaticism is irrational, unrealistic, and destructive.
They've prevented just about anything practical, from no drilling, to no new refineries, to placing the U.S.'s largest deposits of clean coal off limits, to no nuclear power, to you name it with the only 'allowable' alternatives being pie in the sky fantasies that, even if they could be done, would cost a hundred times the current 'crisis' with a corresponding collapse of most economies.
The politicians, certainly, because their prime motivation is pandering to public hysteria and conspiracy theories.
I find it stunning that people have, all of a sudden, forgotten that the majority of oil production comes from nationalized oil and OPEC countries. The 'oil companies' couldn't lower the price if you put a gun to their heads.
More like thousands of factors not taken into account and, in particular, the ones that count.
Here are a 'few' things not even 'suspected' in your ratios. Katrina knocked refinery capacity offline and it's not recovered yet.
In addition, refinery maintenance normally done in the fall was prevented by Katrina and, so, is having to be done now, further reducing capacity.
The government, after mandating refineries re-work their entire processing (not a '0 cost' thing) to accommodate MTB gasoline is, this year, mandating they stop using MTB and switch to ethanol. And, to make sure that's domestic ethanol production, imposed heavy taxes on ethanol imports except we don't produce enough so we have to import ethanol anyway plus pay the high taxes on it.
The point here is not to give 'all the reasons' but to demonstrate a few reasons why 'command economies' don't work.
The problem is that your entire premise is invalid. Component percentages are only useful to tell you what the current percent content is but they don't explain why nor can they be used to predict anything.
As a simple demonstration, if the taxes were eliminated your entire set of calculations predict different results even though the remaining costs are all the same..
Another example, refining is not a '0 energy' process so increases in oil prices increase refining costs. And transporting product isn't a '0 energy' process either.
You've actually hit on two aspects that make all the punditry utter nonsense: that supply/demand-price/cost is *not* linear and not just "extremely complicated' but beyond 'understanding'. By that I mean, it is fundamentally impossible to know/take into account all the factors, interactions, and consequences. For example, force a particular price and you create shortages, and prevent alternative substitutes. Decide you're going to 'incentivize' alternatives and you invariably incentivize the wrong things because you have, a priori, decided what the alternative 'should be' rather than allowing the vast creative wealth of the world, and markets, to 'find it'.
I expect they'll pander to the worst instincts of the voting public, fueled by demagogues who see any and everything as an opportunity to gain power at whatever expense to the public good. And the public are co-complicit in their unrealistic demand for a zero risk, zero cost world along with the wholly unrealistic expectation that governments can 'mandate' manna from heaven.
