In this case, it's not so much about more ICs (although we do need more right now), but it's who's making the ICs. The US is trying to ramp up their internal production capability, rather than depending on Taiwan as heavily.
In an era when 1/2 of the Western world hates Western civilization, I'm not sure that it matters anymore.
Of course, in the long run, it's all just fodder for a history book. The further out you go, the less the details matter.
If the CCP ever decides it's time to take control of Taiwan by force, they could. It's the economic backlash from the rest of the world they are currently worried about, not military resistance. Although I'm not sure just how much they even have to be worried about economically considering how the world has handled recent CCP atrocities.
