Because they do not fix the underlying causes; and also they create perverse incentives. Most companies are in the business of extracting money and will see this as such: an opportunity to extract money and the product is bureaucracy checkboxes. It would make more sense, in this personal view, to restrict sales to domestic production only and make sure the field is even for competitors to out-compete one another. This guarantee the dependency aspect at least (as you already restricted yourself!).
Another solution: Move the manufacturing to a near-shore and friendly country (ie: Mexico or Puerto Rico) and keep the design part in the US. But of course, that wouldn’t be as politically popular and wouldn’t create the extraction opportunity (which lots of companies will want to benefit from).
