I am precisely saying that we need to prioritize. I would rather survive the summer and not fly far away on holiday than die in the summer.

Well big cities are a problem, and people working in services definitely rely on a society built on abundant energy.
I don't know exactly what the solution is. What I know is that our society is built on fossil fuel, and not only those are limited, but they are killing us. So we need to remove fossil fuels. Then looking at the numbers, it appears that we can't reasonably hope to replace fossil fuels entirely. Hence we have to use less energy, hence we have to degrow.
