> Efficient market hypothesis is based on humans acting rationally with available information.
I'm not claiming markets are efficient, or that all humans have access to the same amount of resources or information, just that there are many different incentives out there for people and there isn't a one size fits all.
> Ex: clearly we have done poorly with carbon emissions and global warming, and now we can only hope that throwing money at the problem can solve it.
Even with this, not everyone has the same perspective or the same exposure to the downsides. Not everyone will throw more resources at their problems, some will more than others, some will collect it and squander it more than others, no matter their ends.

> I'm confident society will make it out alive, but at what cost.
The cost is irrelevant, because whatever it may be, it's not going to be born by everyone equally, some will come out ahead and others wont (i.e. if ones family member bought a bunch of land [and didn't lose it through war/confiscation/default/etc] in 18XX with x paper notes, they'd be better off than someone who just spent equivalent x paper notes on a consumable in 18XX). Not everyone will be exposed to inflation because some people are hedged, or live in countries where the value of the dollar is constantly growing wrt what goods they can purchase locally with dollars.
Events are always going to happen, and everyone will respond differently to them everytime. Sure pockets of consensus will form but to expect it to be prevalent among everyone is highly unlikely, and hoping for such to happen is a sisyphean task.
