There are also a lot of geopolitical interests in helping Intel succeed. As much as investors might balk at Intel today, the amount of money that Western governments can toss at the problem is effectively infinite. (Looking at Defense contractors as an example; horrendously inefficient, but tax revenue is effectively perpetually guaranteed to keep flowing.)

It's silly to frame it this way, but even though the US and allies pay gobs for planes like the F-35, it's also what continues to allow the stream of taxable money to continue.

I view Intel in a similar light. Even if they stay inefficient, there will still be money for a long time because the West needs a way to be self-sufficient. The cost of not having a backup is too high (tens of trillions of dollars when I last looked into it).

It's a weird market that doesn't obey a lot of the conventional rules of capitalism. Yes, it would be better if Intel were able to compete without government subsidies, and maybe they will. But even if they don't it's very unlikely they'll totally crater because of how central this "power" is, and TSMC will never cede full control of their latest tech until the UN recognizes Taiwan as a distinct entity from China (imo).
