So how hard would it be to build another primer manufacturing facility? Three simple pieces that should not be that hard to create.
It would be very hard when the hoarding is (inevitably) over. Just like it has come to an end several times since the 90's. Manufacturers have learned that lesson already.
Also, this time around there is a supply chain issue with the Wuhan Virus slowing down all kinds of production. There are spot shortages in building materials, for example.
