An added complication is that pure silicon in the required quantities is not cheap.

The amount of silicon we're talking about here is only a couple of cents per device

'16TB' of silicon at current rates is not a few cents, not even close.
Sure it is, where do you buy your silicon wafers?

64L 3D NAND flash is about 4.40Gb/mm^2. 16TB = 131,072Gb. 29,789mm^2.
70,686mm^2/std 300mm wafer.
Roughly 2 dies/wafer, with exceptional packing, and don't account for defect rates.
Average $0.74/in^2
109.56in^2/std 300mm wafer
81$/std 300mm wafer
roughly 40$ in materials BEFORE you even start talking about the processes to build up 64 layers, and everything else.
