The PRC could blockade Taiwan rather than engaging in the enormous task of outright invasion, but you're right, the resulting economic fallout would be immense blowback to them. China's government throughout all this, regardless of Xi's rhetoric, has been engaging in slow and steady, non-disruptive actions. Saber-rattling with military exercises is one thing (there have been multiple Taiwan Strait crises already in past decades), engaging in open war would be hugely disruptive both to the international order and to the international trade that the PRC has built its rise upon.
