Sure, but the point of this part of the blog post is that there is a minimum viable sizes for modern industrialized civilization, and it is bigger than Australia (pop. 24M), and probably even Russia (pop. 144M). Russian can't itself manufacture all products it needs simultaneously even if it could do it for any individual product.

Folks in this thread seem to have mistakenly interpreted this as a value judgement about Russia from the author. "Russia is sophisticated enough to produce any of these products!" is a retort to that claim, buts it's completely besides the point.
