> A domestic monopoly might not be the only way to prevent a foreign monopoly, but it is a guaranteed way so it makes sense to let it proliferate.

It isn't in any way guaranteed, and you just listed an example of it failing. Intel used to be the world leader in fabs and now it's TSMC, because that's what happens if you let the domestic market consolidate until the incumbents feel they can rest on their laurels and then a foreign competitor throws down the gauntlet.

> If you want any sort of control in the industry (and not be bullied for access like we do to China), you need to be the biggest buyer / operator of those chips.

Or you need an actual diverse competitive market so that that sort of bullying doesn't work for anyone.

Suppose the GPU market had a dozen or more companies with significant market share and four of them were in the US. Then it doesn't matter where the other ones are, nobody can deprive the US of GPUs because the US can always get them from the US vendors or have them increase production.

It would mean that the US can't do the bullying anymore because then others could buy from the non-US vendors, but what is the rest of the world doing not causing that to happen on purpose?
