And that's just one of the many ways that hydrocarbons are woven into critical parts of the global economy. You can't just snap your fingers, make oil go away and expect modern civilization to keep existing as it currently does. It took ~150yr to get the oil industry where it is today and that is with a massive financial incentive. People need lubricants, tars, fuels, plastics, everything that oil makes cheaply and well. In the absence of strong organic (not artificial, i.e. regulatory compliance) incentives to stop using oil it will almost certainly take much longer than 150yr to reduce oil usage for energy/fuel to negligible levels. We will likely never stop using oil for plastics, fertilizers and other "critical to modern civilization" things until something that's cheaper and equivalent or better comes along for every last use case. Keep in mind that whatever we have next will have tradeoffs too.
