Linear scaling of any project large enough to disrupt an industry (as is being suggested here) is a pipe dream. When you are trying to scale up something that big, you eventually get beyond economies of scale for the required infrastructure and feedstock, and as a result, increase overall demand, which raises prices. You only get near-linear scaling for a very short, initial "ramp-up" period. Beyond that, you start cornering markets, which makes prices spike, not decrease or even hold steady.
