Well, true, I guess we won't see a lot of market crashes in consumables, but, as you point out, there may be arms industry crashes, and plenty of possibities for similar crashes in goods demanded as inputs by factories, or for construction, so when government procurement dries up, the industry crashes. Remember that the reason none of this possible in Vicky 1 was because you didn't actually need any demand at all in the World Market to sell your stuff! Assuming that now every good has to have someone to purchase it (I hope) to be actually hold on WM, this should work to create bubbles.
Of course if you can still sell stuff to the Martians, then we've got bigger problems with the trade model than absence of bubbles.
