How does making something illegal counteract economic forces? Hint: Look at Soviet Bloc economics. They imported high tech goods even after spending loads of money on trying to build them internally. I would agree that onshoring more of the supply chain makes a lot of sense, but I think it must be an economically viable solution. I don't know exactly how to do that, but things like having a guaranteed market (like we do for food) might be part of the solution.
