> How could that be detrimental for human flourishing, I ask? Are the burgers essential for humans to flourish? I don't think so.
Disclaimer: I decided to interpret the comment as disagreeing with me because it seemed like the most plausible interpretation giving the ambiguous potential use of sarcasm, but it's very possible I misinterpreted.
The burgers and the farts were an attempt at humor.
A much more serious consideration (also in my original) is heating our homes. If you have ever been homeless longer than a day or two during cold months in a cold place (I spent 6 months this way), you pretty quickly learn how important modern climate controls are. I don't see how you can "fluorish" when you're freezing your ass off. Good luck getting the sleep you need to perform either physical or mental work, which currently is needed in order to fluorish (unless you think the homeless on the street are fluorishing). If you're lucky your employer will be able to heat their office so you could live there, but not everybody works for someone like that. The wealthy would be able to buy whatever they needed (electric heaters, solar panels, battery storage, the high labor costs of retrofitting all these things, assuming these are even still available after the long chain of dependency is broken) but the vast majority of people would not. Human fluorishing is not just comfort for the wealthy. The average person's life matters. Much of what advances our human condition come from people who aren't born into wealth.
How exactly do you propose to heat the average person's home when all fossil fuels are no longer available? And any derivative products of fossil fuels such as plastics? Keep in mind even bio-plastics made from corn and other products would not be nearly as available since we would lose orders of magnitude of production capacity by no longer being able to use fertilizers, tractors and other machinery, etc.
I guess we should probably establish what "human fluorishing" even means otherwise this discussion is pointless. If your idea of human fluorishing is where a massive perecentage of human labor is doing farm work again like in the 19th century, or going back to feudalism where we all work the Lord's land and pick his crops. My definition is where human quality and standard of life continually increases. We're not perfect right now (especially with life expectancies in the US dropping) but our current situation would look like a future paradise compared to what we'd have without any fossil fuel.
