There is no way that Taiwan (or the US) would just hand over TSMC intact to the Chinese. With SMIC stuck on 14nm, with 7nm and 5nm in development hell, the EUVL machines at TSMC would be the real goal in an invasion. No way those would remain functional even if China did take the fabs. And its not like China could then go to ASML and ask for spares or replacements.
