> US it just might help bring about a cultural shift away from extreme consumerism towards something more sustainable.
If the US's best defense against a China-initiated economic war is to give up consumerism, that doesn't give me a great deal of hope for Taiwan.
More generally, it would be great for manufacturing to move back to the EU and the US. But that can't happen on the scale of months or even years; in a war with China, we'd face huge supply chain disruptions for the duration.
> They are armed with missiles to the teeth and they can hit some rather sensitive places in China.
This isn't a realistic appraisal of Taiwan's military capabilities. China dominates Taiwan on all aspects of military power; fanciful ideas about blowing up the Three Gorges Dam aside, China doesn't worry too much about Taiwan's military.
> I expect brain drain and leaving rest of the Taiwan to China while officially protesting it and banning Taiwanese products from US/EU markets for a couple of years to help local spin-offs stabilize.
As bad and dumb as this outcome would be, China would consider it a total victory.
> Taiwanese might choose to fight, in which case US/EU will happily supply weapons.
You have to get those weapons to Taiwan somehow, and Taiwan would need to be able to launch them from somewhere. China has effective countermeasures to both if American engagement is limited to that.
