Regardless of whether it is Crypto/AI/etc., this would seem to be wake-up call #2. We're finding the strangle-points in our "economy"—will we do anything about it? A single fab in Phoenix would seem inadequate?
And regardless, you could flip it around and ask, what will we do in x years when the next shortage comes along and we have no fabs? (And that shortage of course could well be an imposed one from an unfriendly nation.)
