Having now read it, it doesn't deal with my original point which is essentially:
Libertarianism risks outsourcing manufacture of vital goods to foreign states of dubious intent, leaving domestic industry to die with no means of resurrecting it in an emergency.
The closest the above reference comes to dealing with this issue is:
* with free international trade, nobody will want to attack Libland because they can get at all its resources cheaply anyway, and
* Xia won't actually be able to invade Libland because they'll be too busy dealing with their own citizens, who, impressed by Libland's affluence, are too busy trying to convince Xia's rulers to convert to Libertarianism.
