> I think you'd end up breaking up (or trying to) Lloyds of London, Spacex, Fedex, DHL, Boeing, Panasonic, ASML, Google, Apple, and many other very specialized companies.

I see exemplars and no counterexamples.

Boeing turned to garbage when it took on McDonnel-Douglas--we were better off with the separate companies. YouTube not being bought by Google means that you don't have a single giant ad juggernaut and the copyright infringement that goes along with it. Apple being busted up means we have a division that actually focuses on computers in their own right rather than being a vestigial graft to the phone services division. Fedex was enough of a monopoly problem that Amazon bought carriers and, very painfully, set up its own delivery system.

> The world can barely support 1 ASML, imagine if we had to pay for 5 of them.

So, you prefer that we are two Chinese drone strikes from having a chip economy meltdown?

This is the kind of stuff that absolutely needs diversity. And part of the reason the ASML stuff is so expensive is because it doesn't have enough volume. So, for example, if the US had multiple fab lines that could consume the ASML machines, that would reduce the costs for ASML.
