The thing is, pretty much everyone relevant assumes it is a bubble and that eventually large players will end up facing mob justice. That's why the hundreds of billions of $ IOUs are getting passed around like hot potatoes, and that's (in addition to ASML, the key part of anything EUV lithography, being booked out for years) why no one is planning to construct dozens of billions of dollars worth of fabs.

In addition, the know-how is concentrated in Taiwan. You literally can't train enough people in enough time to move everything out of there.
