The catch is if you started today with plenty of money (billions of dollars!) and could hire the right experts as you need them (this is a big if!) there would still be a couple years between today and producing 150 wafers per house. So the question isn't what does the math look like today, it is what the math looks like in 2 years - if you could answer that why didn't you start two years ago so you could get the current prices?
