I mean, I don't disagree that it's awesome and that waste isn't the real problem, but...

Productive enough to outcompete cheap exports from the imperial core.

The cheap exports are a result of international finance fucking over the labor in the producing countries who are locked into their shitty loans by corrupt puppets of Western imperialism. Those cheap exports are just the international trade equivalent of Loss Leaders. Making a cheaper competitor isn't going to stop the coups or the NGOs or the right wing death squads. The prohibitive problem isn't the cost, it's the barrel of the gun pointed at the third world holding them hostage to the system. If anything, I'd say this is more likely to help those states who are already exiled from the western community like DPRK, Cuba, and Venezuela.
