The issue is timing. Our financial system is in danger of failing in the short term, as our debt-based system of financing everything in the economy collapses. We have reached the point where incomes are not high enough to take on more debt. Governments have been trying to cover up this problem with Quantitative Easing (QE), which has the effect of lowering interest rates.
Unfortunately, QE has adverse impacts as well, including creating bubbles in prices of many things, including stocks on the stock market and land prices. The US government has recently tapered to zero its QE program, while otther QE programs elsewhere continue. The loss of the US program is part of what is causing the price of oil and the price of all commodities to drop. If the US government goes forward with its plan to raise interest rates next year, commodity prices including oil prices are likely to drop even further. This will have a very adverse impact on oil exporters and on the US shale industry.
If we had a long time for transition, and a financial system that would support transition, I might agree with you about transition. Everything I can see says that we are headed for a near term major-debt problem, however. This might be rising interest rates, making new debt unaffordable. Or it could be defaults on existing debt, particularly on commoditiy related loans. It also could be problems with derivative defaults, that get passed on to other parts of the financial system.
The US government and other governments have been severely criticized for bailing out banks and insurance companies in 2008, so that they are intent on getting out of supporting this risk. So there seems to be a substantial risk that this time around, failures will feed through the system differently. I don't know exactly how this will work. It could mean that businesses with large bank balances (intended for payrolls) will lose a major share of their bank balances. We could see failures of important businesses, such as electric utilities. Some reports say that pension plans could be affected as well.
So I think we are on the road to extremely severe near-term debt-related problems that will put an end to the possibility of a transition to any other fuel type. I know some poeple say, "All we need to do is put in place a new financial system." This is more easilty said than done. For one thing, debt is a necessary part of such a system, because businesses have to contract severely, if they are to finance projects only on accumulated earnings. We really need economic growth to keep the debt cycle going, and it is economic growth that is failing now (indireclty because of diminishing returns, or as some people think of the problem, falling EROEI).
