Self sufficiency for products that are the lifeblood of your economy is attractive to governments. Any of the things you describe can easily be replicated locally, fabs much less so. Even more to the point is that it gives countries the chance to develop a high value competitive advantage that others cannot replicate. Places like the EU would argue that they have the human capital to compete globally but they don't have the industry because of historical factors.
