On the bright side, this would probably happen only if the host country doesn't block these crops and continue enforcing those patents as the situation gets dire. A sane gov. would pull the brakes pretty fast. On the dirty side, a gov could be forced in that situation as a condition to receive foreign investment or other critical foreign intervention. We've seen it happen with water infra built under a condition of monopoly, an puting the country's water at the mercy of an international company.
