In the food industry there (generally) isn't a big isn't a big prize or defensive moat for being the first to develop a new product at scale. Especially at the national level.
Many capital intensive internationally traded industries are different. Once overseas competitors have been through a few innovation cycles and sunk tens of billions of dollars into product development it's basically impossible to catch up. Even with government support.
TSMC is the canonical example, but similar principals apply with Amazon and other big tech companies with high infra spending. More subtly, industries with high marketing costs are very hard to penetrate at scale when an incumbent has reached a certain depth. See enterprise software with MSFT or high fashion with LVMH.
As well as losing the opportunity for economical development in a new industry, dependence on overseas imports for critical industries creates geopolitical headaches.
European governments recognised this risk in aerospace a few decades ago, and the Airbus project saved Europe and the world from a Boeing dominated international passenger jet market.
