I don't think it's that simple, because the effort necessary to employ the different choices are very different.
Stopping cargo going out of Taiwan is rather cheap. Unguided rockets and aircraft from your homeland can do a lot. And then they just have to defend near their home land while waiting for their opponent to run out of resources.
At the same time, as we can see here, it takes 4 years to go from acre to functional fab plant after planning and negotiations. And any kind of war to regain control of the chip supply lane is a significant drain on the chips and systems reliant on the chips you have.
