If I'm not mistaken, I think that all the pieces have to be manufactured in state from steel made from iron that was mined in state, and possibly even with tools made in-state.
Note that I do not agree with this interpretation, I am simply of the belief that it is what is currently in use by our country's government.

Don't confuse me with the facts. I am happy just dreaming...
In the real world, you would also need a state government with guts and an understanding of their own place and power before the behemoth of the federal government.
So, yeah, dreaming.
