It is not just Taiwan's advanced manufacturing that is critical to the free world — an enormous amount of shipping for Japan also goes through the Straits Of Taiwan. This is just part of the reason that the US Navy frequently runs freedom of navigation exercises through those waters.

Mere reduction of the criticality of Taiwan's advanced manufacturing will not eliminate Taiwan's geostrategic importance.

Plus, the CCP's insistence on being an expansionist authoritarian state is reason enough to contain that expansion, to prevent further resource gains.

So far they don't feel that expansionist. More likely they just don't want US to be able to cut them off from the rest of the world by naval blockade.

"don't feel that expansionist"?!?

Sure, if you ignore their military actions and treaty violations in Tibet, Turkistan (Uyghurs), border conflicts around the Himalyas and India, Russia (border conflict), Korea, Vietnam, everywhere on the "9-dash line", Canada and the US (where they are putting up remote "police stations" to intimidate anyone expressing opinions they dislike)...

CCP has a highly consistent history of being as aggressive and untrustworthy as they can get away with. Anyone trusting them is a fool.
