I mean it's game theory. Once you start allowing such things you simply have to always allow them. If you allow China to bully you into not visiting Taiwan, they will start bullying you into something else. Neither side will actually do war so it makes sense not to fold

Ah yes, but like others have pointed out, China did in fact allow US ballons over their territory.

"Neither side will actually do war so it makes sense not to fold"

And neither side wants war with each other, but if either side is pushed more and more into it from internal and external pressure, than I sadly would not rule out that possibility.
