We know that ASML doesn't ship high tech machines to China, it only ships low tech ones. China in return holds the world hostage by not producing enough chips. With enough subsidy, I think we could ramp up production to meet demand.
I also don't understand that the key companies are monopolys. It all seems a bit planned to me. Place the chip manufacturing company in Europe, chip factory in Taiwan, assemble in China. I feel like someone planned to distribute these technologies and infrastructure to avoid having one country having it all.
I know I cannot support my argument, but this is a gut feeling I have.
OTOH, nobody can reasonably explain why there are unsolveable real bottlenecks in the supply chain and why it would take years to resolve. Throw resources and people at it. This is not just one company with limited resources and a single goal. We should fund the semiconductor industry.
