I think it will still be challenging to make the economics work, policies that assumed growth will need to change (such as assumptions around affording welfate programs). Otherwise I agree, there probably should be an equilibrium point to float around that they can aim for.

Right, it's the first point brought up every time in rebuttal. But, when have we not had to make adjustments to policy when circumstances change?
The argument against a sustainable population basically boils down to, "but, then we'd have to make adjustments to policy!" Which is not the slam-dunk some seem to think it is.
