Your article by Tanner Greer, one of the most ardent supporters of Taiwan military changed his position last year that Taiwan can repel PRC alone. Same with Ian Easton. There aren't any credible experts left there who still thinks Taiwan can stand alone, and both Greer and Easton were holdouts that were far from credible in the subject matter in first place. Regardless, I think there's too much obsession and wank ove…
CCP can win a successful invasion, but turning Taiwan into dust will backfire hugely. Starving Taiwan into submission is at best case scenario a massive hit to China's foreign and economic relations (ensuring a block analog to NATO just to counter China) in order to get an economically devastated province, with possible internal stability hit since eventually Chinese citizens will know what it cost. This isn't a good…
I think you massively underestimate the psychological effect of seeing a first-world country reduced to a third-world country if Taiwan doesn't surrender very quickly. Also, the realist concern is classic 'balance the strongest power' dynamic.
I don't think China has to worry about an outright official blockade, but you'll end up with a Cold War rerun and Chinese companies being unofficially driven off the West, SK and Japan working together, possible SK/Japan nukes at the very least. China played a lot of cards trying to keep other countries not ganged up against it, best not ruin it to get a devastated province. Simply put, any starvation scenario where Taiwan decides to fight will be a disaster for CCP too.
So I believe any CCP strategist understands it's better to sacrifice men and take Taiwan outright without turning it to Yemen (a preference which you stated as well). A quick enough operation will be ignored by the world for reasons you provided, and they may well be in a position to do that soon. The 'wait out months/years and publicly starve out Taiwan' is incredibly poor in comparison.
