I agree in principle, but the only thing that keeps China from invading Taiwan is the ability of Taiwan to defend itself (with international help). Explicit US (or broader world) recognition of the ROC doesn't mean China wouldn't invade anyway. Hell even if China would officially recognize the ROC as legitimate, that wouldn't mean they wouldn't invade in the future (they have no problem ignoring past treaties when it suits their interests). This is all just a political game by China to present a narrative that bends reality to pretend they're not invading and taking over a country that neither threatens them or wants to be ruled by them. So while I agree with you it's pretty disgraceful of the US and other countries to advantage themselves through trade and cooperation with Taiwan without officially recognizing their sovereignty, I still think the most important would be if more countries at least supported them in their defense against Chinese aggression.
