I'm confused by this take. Who is threatening Japan with cruise missiles? Certainly not China or Russia. North Korea, perhaps.
The primary reason that we're concerned about semiconductor fab concentration in Taiwan is that China has consistently stated that it is going to invade Taiwan at some point (and that could be 2049 or in a few years for all we know). This is completely outside of any hypothetical scenarios of who lobs cruise missiles at who during WW3.
You can make the point that relying on semiconductor manufacturing outside of your country/coalition is a bad idea for military self-sufficiency, and I would agree, but that's a much more diffuse risk than the very specific scenario that is driving the CHIPS act and concern about fab concentration in Taiwan.
