Yes, but...
Did you note that Elon said they couldn’t build a Model Y, Semi or pickup truck right now anyways because they are cell supply constrained? And that they “haven’t figured out” where and how they will get cells for the Shanghai gigafactory?
My point being that battery cell supply seems to be their limiting factor for the next while, not capital. That begs the question, why? We know that Panasonic doesn’t like to move as fast as Tesla (what company does?), and they needed to be dragged across the finish line for the Gigafactory. Other than Panasonic’s reticence, the other issue could be raw materials supply. It is possible Tesla/Panasonic are reaching a point where they can’t source battery cell raw materials cheaply enough for the next while, until more mines get developed.
It would be interesting to pose these questions to Elon the next opportunity anyone has.
