If fossil fuels rise, the cost of transportation of EVERYTHING goes up and the entire economy explode. Do you want 50% annual inflation? What you saw during COVID would only be a taste.
Your comments are an insult to readers' intelligence. Efficiency is good. Cutting fossil fuel use ASAP is crucial for the future of humanity. Shifting demand from air travel to high speed rail and from air cargo to ocean freight are unalloyed goods.
If you want to bleat nonsense about imagined 50% inflation, please go do it on twitter.
