Earlier quoted context omitted.
If Zeus himself descends from Mount Olympus and says to you, "I am going to reestablish slavery in society. I will select slaves by lottery, and when it's all over most of the population will be held in the bonds of slavery. No one will remember a time before slavery. It will be as though it has always existed. I will never let slavery be abolished again. I give you, and you alone, the choice to be free or enslaved."…
What does this have to do with anything? I could answer the question as you ask it (of course I would choose to be free), but I don't see how it's relevant to this discussion, because in the real world, slavery is not dictated by Zeus, it is enforced by some humans on other humans.
For much of history, civilizations and other groups of people took conquered peoples as slaves to support the conquerors' lifestyles. The slaves served as the cheap energy that today has been supplanted by fossil fuels.
Our Western lifestyle is predicated upon these fossil fuels in much the same way that prior societies' lifestyles were based upon slavery. Slavery has undesirable characteristics that we (being dependent on it no longer) are free to scorn the evils of.
Fossil fuels also have undesirable characteristics: they're polluting the atmosphere, polluting the water, and releasing boatloads of greenhouse gases into the atmosphere. Sea levels are rising, coral are dying, and storms are projected to continue increasing in magnitude. Perhaps you've heard the economics saying, "There's no such thing as a free lunch."
You and I are so utterly dependent on this source of energy that our brains can't fully comprehend the consequences of choosing the alternative. And there's absolutely nothing we can do to convince anyone else to stop using fossil fuels. If you're anything like me (and other normal humans), you ignore the costs associated with your actions and continue to use fossil fuels for transport, for food, and for electricity to power your electronic gadgets. To change your lifestyle would require severe unpleasantness.
