I don't know exactly what her book says, but how do you guys see capitalism as something which can just continue in its current form without end?

Oil is, by definition, a limited resource. BP projected 53 years to go at current rates, https://www.ibtimes.co.uk/world-energy-day-2014-how-much-oil-left-how-long-will-it-last-1471200 in 2014. That may seem like enough for you, but if you have kids or grandkids or know people thinking about having kids, 2067 is not an imaginary date anymore. Anyone born now will definitely be dealing with this.

And yes, you can say, "we can find more oil, we figured out fracking and deep sea drilling, we'll find some other method!" - but that isn't the point. That only extends the problem a few more years. It is going to run out. It's made of fossils, and until we have another few million years for fossils to turn into oil, we are using up the last of a limited thing. It might make a lot of money, because rich people will pay the most to have it, but it's not a fair way to divide a scarce and valuable resource.

I don't think anyone wants to "overthrow" or reject the rule of law. People want to reign in the greed & competitive materialism that is driving the overuse of our limited resources and find a better way to organize and distribute our shared potential.

Maybe it's impossible because humans are too corrupt, but all the same, capitalism is going to have to go through a major overhaul as the reality of oil scarcity becomes more obvious, and we can either try to plan for it, or deal with a lot of chaos, war & terror.
