Xi (more so than his predecessors) is quite happy to take a short term loss for (what he sees) as a long term gain. In addition, he would love to be remembered in history as the man he reunified China.
Basically, if we "built the wall", they'd still have all the stuff, and we'd have increasingly more worthless numbers in our bank accounts.
Relying on one country for most of our production needs is stupid.
If it stops being a critical national security issue for us? I don't really care. Like, I'm for self-determination and all that but I don't care more about Taiwan than I do about Yemen, and I and the rest of America definitely do not care about Yemen.
No it isn't. China can occupy Taiwan without killing thousands of US soldiers. That matters, politically.

It's not about Taiwan, it's about China. If they successfully annex Taiwan they'll eat the rest of the world too, one bite at a time, and drawing the line in the sand will get harder and harder.
