China doesn't want Taiwan for TSMC. They want Taiwan because they see them as a rebellious province. In their mind, the Chinese civil war never ended and that island is the last bastion of the Kuomintang. One way I've heard it described in a way that is easier for Americans to understand is; Imagine at the end of the American Civil War, a confederate army retreated to an island like Cuba or Hawaii, they took it over and have been calling themselves the real America ever since.
I'm not saying China is right in wanting to invade Taiwan. But that's closer to their real motivations than anything having to do with economics or technology. And its important to understand your potential adversaries motivations because that will inform their decisions and tactics.
