The nominal price of crude oil is largely irrelevant whether measured in US dollars or any other currency. What matters is petroleum's relative value to other commodites as well as wages and incomes, and, of course, physical shortages.
Commodity Price Inflation

Commodity Price Inflation in Euros
Notice the effect of the weak US dollar pales in comparison to real inflation-adjusted prices. That is actual demand outpacing readily available supply. Note that potential demand is always greater than actual demand. High prices ration demand where as available supply is limited by natural, physical and manmade shortages.
Unfortunately, I do not have an updated version of this graph to reflect commodity price gains in the past one year. However, just looking at a regression to the mean (say around long-term bond yields) that energy and commodity prices still have much further to rise most likely at the expense of property and equity prices.
I apologize for using different time scales for comparison purposes, but it is hard to get the complete data much less prepare and size those graphs.
That fact is that governments are addicted to the revenue from oil whether that is royalties paid to producing nations or taxes levied on retail pump prices. Were we to see a super-spike in crude prices governments can lessen the blow to consumers in a stroke by rolling back taxes. But they won't because they need the money.

$this->bbcode_second_pass_quote('', 'T')he only point I would make about economics in general when discussing peak oil (and I've made this point in various ways before) is that economic analysis simply provides red flags in the form of high prices too late. I have no suggestion regarding a better system for determining prices and how to allocate resources, but this problem of providing dramatic market signals in the form of high prices 10-20 years after the market would have needed a signal in order to actually do anything about the problem is troubling.
I suspect that an economist would say that it is the job of government to correct a market failure like this by imposing the necessary taxes to provide the appropriate price signal (which is sort of what Europse has done, I suppose) if this is in fact a market failure, but I don't think the U.S. government is anywhere near that perceptive.
So we are sort of left with a good tool (economics) when we need a great one (enlightenment?). Or maybe human nature is the real problem, and so long as humans are the ones searching for a solution, one will never be found.
Basically, you are right. Human nature and politics always trumps economics in the short-term. But that is true wether you are in a command and control economy or a social-democracy with a market economy. We know that we are living beyond the planet's ability to support us in the long-term. Doubling or tripling nominal prices would not make a difference to that unsustainability, and in any case much of the world's population could not afford to pay those higher real prices in any case, so the point is mute.
One can curb fossil fuel demand through higher real prices and carbon taxes, etc., but if no one can afford them that is another story. Why don't governments just mandate vehicles that get unlimited mileage with zero emmissions? You may as well blame it on the engineers for not developing a cleaner alternative to petroleum sooner, and at a reasonable cost that everyone can afford! ; - ))
