For me, you are voicing principles that have been engineered in you. No one can choose constraint, etc. You say there are serious problems, but you have precisely zero personal evidence, like everyone else. You only have the (self-serving) stories that the authorities tell you. Oh, and, they will be doing the constraining. And you will pay. Its a good gig, if you can get it, I guess...
I can’t speak to what the other person was thinking.
But in relation to geopolitical problems of the dependence on fossil fuels it’s perhaps most obvious to point to Putin’s war in Ukraine and how he calculated he’d get away with it because of Europe’s dependence on Russian oil and gas.
That’s without even starting to calculate the cost of climate change.
