Won't banning H1B1's prevent new factories in the US?

Let's say H1B's are banned, and I'm in charge of opening a plant to build X in the US for a company in Germany. There are 0 plants that produce X in the US currently. Right now what every company does is:

1. Build factory using US labor

2. Employ 95-99% of future workers from the US who will work on the line

3. Get H1B's for a team of manufacturing/industrial engineers who designed the line if it is brand new...and/or get H1B's for people who have worked making X in another country

4. The H1B's train the new Americans on how to work on the line to produce X

5. H1B's train and oversee the transition from them being in charge to having Americans be in charge. This is where you hire/train the last % who will take over for the H1B's in management when they return to Germany

6. By 6 months it should all be 100% US domestic workers

Without the H1B program there is no way for me to bring over my engineers and line workers to train the new guys in the US. There is no way for them to work on the line w/o specialized training and nobody in the US has that training because it is a new line designed in Germany.
