"US Government is also got TSMC (Taiwan's semiconductor fabs) to build an Arizona fab-lab. Look, even Taiwan is scared of possible conflict and is hedging on the physical safety of the USA."

I don't think that's the case, as I understand it this comes from the US wanting to onshore some of TSMC's capabilities and Taiwan screwing up electricity production on the island.

It does Taiwan the government and ruling class no good whatsoever to place assets beyond the PRC's military reach, rather the incentives are entirely opposite of that. The more valuable TSMC's fab lines there are, the more incentive the US has to help with the ROC's defense, or war if it comes to that. Which in the case of torpedoes from attack subs can even be done with some plausible deniability.
