People like you look at these things as if you just shift numbers around on an excel sheet. There is still physics and geography involved here. German industry is already hardly competitive in terms of price, what do you think happens when those raw materials are 10 times more expensive?
Now there is a price crunch for LNG tanker charters further pushing up prices. Also it's so disingenuous. Indians are now refining Russian oil, selling it back to Europe but Eurocrats and lying politicians get to pretend they're going off hydrocarbons.
With oil the solution is trivial. Switch to electrical cars while generating electricity for them with modern efficient coal plants using German coal. Not only it will be cheaper and reduce geopolitical risks, but it will drop CO2 emission as well.
