This is an impossibility. You can just build ten smaller factories to scale up and get at least a linear gain. No economics of scale just means that you can't get much better than linear, but in nearly all cases you at least get linear scaling.
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.

No it isn't. Your "solution" is a different thing. A collection of smaller facilities is not the same thing as a larger facility.
Read the article. IIRC, it's talking about the limits of how large you can practically scale a clean room.
