Currently chips for civilian and military applications often come out of Taiwan.
The strategic and political situation of Taiwan is -fluid. Losing these fabs would be a heavy blow to the west both economically and more importantly qua military defense.
Thus extra fabs in other (western) countries are pro-indicated for this reason alone. It's insurance.
I believe the importance of Taiwanese fabs is very overstated. Taiwan is mainly a (geo) political matter.
(I don’t agree that hedging against potential action by a single major strategic adversary is a strong move toward autarky, however—if, say, Canada had tons of fabs instead of the precariously-perched Taiwan, I bet we’d not be spending so much money on them)
Energy sovereignty is a good reason Europe needs to be getting off fossil fuels ASAP.
However, the on-shoring of chip production is especially for military strategic purposes. Right now a majority of chip fabs are all in Taiwan, and within striking range of a country that likes to rattle its sabers. Losing Taiwan's fabs would be a problem wrt military supply.
right now the panama is at lower capacity due to droughts and the red sea leading to the suez is a conflict zone.
As but one signal, the recent dumping of Chinese EVs has less to do with industrial superiority and more to do with their own shrinking domestic demand. The Chinese market is saturated and consumer demand has slowed.
India's growth is predicted to top China's before 2030, and manufacturing is moving on to cheaper cost of labor economies. Mexico, India, Vietnam. Africa won't be far behind.
There are plenty of other markets for American tech.
One of the theories of China's recent, intense sabre rattling is that demographically they'll be in no position to militarily take Taiwan in 20 years. So it's now/soon or never.
I believe this supposed rush to take Taiwan is more about Xi's personal ambitions rather than strategic pressure.

the fed has a problem. There are two US economies but only one rate.
The 95 v 5% split in the US with the middle class worse and worse is a problem. It'll be the same for China except that Chinese politicians are way more attuned to social cohesion compared to the west.
Western manufacturers have been caught with their pants down, they operated under the assumption car ownership would become a premium thing, like owning an iPhone. Basically thought they'd have a free lunch fleecing consumers.
