> China stages such incursions on a near-daily basis, part of what are termed “gray zone” tactics, aimed at intimidation and wearing down Taiwan’s equipment, exhausting its personnel and degrading public morale.

So probably not the start of a war as could be easily interpreted from the title

Why don't the Taiwanese just ignore these tactics until they're clearning violating territory, then fire a few warning shots?

Genuinely curious why responding to each incursion into the zone around Taiwan is necessary every time this happens?

Yes, anything can be misinterpreted without proper context!
