This actually removes a large part of new colonialism's rationale - the pursuit of new markets. Why bother conquering new regions if the economic benefits are undercut by the cottage steel industry etc. Surely the solution to the instability problem would be to remove intrinsic demand for industrial goods in countries which don't have access to international trade. For example, native peoples would not be interested in buying advanced machinery (or whatever Mfg. is) if they had no idea of its existence or availability.
Lastly, I have sunk dozens of hours into my current PON game so a fix of some sort which DOES have an effect on ongoing games would be much appreciated.
