Hi Charlie. The "three warfares" indeed remains a component of Chinese strategy toward Taiwan, and legal warfare is one of the three. The 2005 Anti-Secession Law is an example. And there has been discussion in China about a national reunification law for Taiwan, although we have seen no evidence that it was raised at the NPC. Such actions are part of China's coercion toolkit that seeks to show the Taiwanese that they have no choice other than unifying with the Mainland and bullying them into submission. But simple passage of a law will not transform Taiwan in the way that it has Hong Kong; China can't manipulate the electoral system or the judiciary in Taiwan in the way that it has in Hong Kong. It can use laws to threaten and inflict limited harm, but it cannot use law to exert control over Taiwan. I believe the scenario you cite is unlikely because China seeks to punish those who are pushing for independence, while keeping those that want good relations with Beijing onside. China has a lot of leverage over Taiwanese businesses operating on the Mainland or Taiwanese students studying there, but it has refrained from taking punitive actions against them--for good reasons.
