If that price is for bare dice, then there's packaging costs to consider, too.

If the target price is $6 per unit, the order size would have to be
around 30,000 units.  It will probably be cheaper to scavenge old
machines for a long time to come, unless some sort of short-run fab
pops up (or unless hobby fabbing with 1980s-sized structures becomes
feasible).
