I'm sure China knows that if they do ever actually invade Taiwan, then there will be hundreds of agents, if not outright military actions, to destroy or sabotage the critical parts of Taiwanese industry rather than let them fall into the hands of the CCP. (For instance, I can't imagine any of the key ASML machines would survive without being quite thoroughly destroyed by thermite to keep their secrets from falling into Chinese hands.)
This would nearly completely cripple the world's tech economy for a decade, but that is far better then becoming vassals to CCP tyranny.
