Lots of words, most of which support that, as you wrote "profits are mission-critical". None of which support "the bigger the better".
Tesla has already achieved the highest profitability in the automotive industry. What they need to do now is increase production as fast as possible. They do not need bigger profits. If they achieve autonomy, that changes all sorts of things, but they have not, and they have no believable timeline to do so. Meanwhile, they continue to take the position that it is various limitations in material supply that is constraining the number of cars produced. So, first principles, they will try to reduce the material required to produce each car.
We shall see where it goes. But I don't believe they're going to focus on making as much profit as possible, nor should they. Maybe if they had a bean counter in charge, but not Tesla, not now.
