Semi is oil now, there's more strategic/geopolitical considerations than supply/demand curve. US/EU/CN do not want Taiwan to have semi dominance, it's not in anyone's interest. Current TSMC position is happenstance due to poor industrial policies that countries are scrambling to address. IMO press releases and capex spending around Arizona announcement suggest TSMC wasn't prepared to built US fab, let alone 6. US pressured them, EU failed to. There's a good chance TSMC/Taiwan will try to delay their silicon shield evaporating for as long as they can. Probably not a coincidence big ticket US weapons sales are scheduled around when fabs would be up. Future will be priority sourcing from domestic fabs, let TSMC whither, by design.
