The point is that foreign fabs are a very real multi-national security risk. Even if we decide that friend-shoring is acceptable, the best 'we' (folks in the US or the 'west') can do outside of Intel is Samsung. Depending on TSMC in Taiwan is a disaster waiting to happen, and it also makes a great power conflict there more likely as the asymmetric advantages increase for non-western powers if they were to capture the island. Game-theory would probably suggest that the west should do whatever they can to bring fabrication home, because subsidizing fabs is less expensive than war.
