Sounds like you've been fed the US anti-China propaganda for the large part of your life as well.
_China doesn't need to invade Taiwan_
1. 50%+ of Taiwan's workforce are white-collar workers [0].
2. There are 3-4 major underwater internet communication hubs in Taiwan [1].
3. There is a substantial opposition in Taiwan that want reunification (~20% of population support directly Li-Wun) [2].
4. China is close to producing industry-grade EUV [3].
China just can:
* Establish a total naval and air blockade of Taiwan using their fleets stationed in Ningbo and Zhanjiang.
* Cut underwater internet cables in those 3 locations.
* Achieve EUV.
They won't need TSMC soon, and with the blockade they can show the world that TSMC is not a reliable supplier.
Within months the political structure of Taiwan is going to crumble, as white-collar workers lose their jobs.
