I’m not sure I want the gov and huge amounts of my tax dollars going to operate federal gov chip fab plants.

That is ultimately what the subsidies amount to.

On the other hand I get your point that it is so heavily subsidized it is practically a de facto situation anyway.

I think the question isn't "Do I want my tax dollars going to X?" (because they're going there whether you want it to or not - semiconductors are an essential industry in a modern post-industrial nation). The question is how you want the business to operate. As a for-profit venture focused on returning the maximum profit to shareholders over the smallest time frame? Or as a public utility, focused on generating a sufficient quota of useful products for a fixed unit cost?

Part of the problem with the Western/Americanized economic system is that the second kind of enterprise is increasingly difficult to find. And where it does exist (the USPS, the state university system, the federal reserve, the SEC/FAA/EPA) there's been so much privatization and regulatory capture that these institutions appear incapable of fulfilling their mandates.

But constantly diverting responsibility for fixing the problem by saying "I don't want my tax dollars involved in this failed thing" doesn't get us any closer to a solution. At some point, the public (and by extension the state bureaucracy) has to engage with our corrupt and failing economic cornerstones. Otherwise, we just become beholden to the nations we import from.

"Let Saudi-ARAMCO handle it" isn't a solution I find particularly appetizing, either.
