Secondly, Chinese military sealife capabilities are only needed to secure the beachhead. Once that has been accomplished, they can make as many round trips as they like with their landing ships to bring in all the reinforcements they want. Hell, at that stage they can use civilian ferries if they want. Let’s not forget that even the British used civilian cruise ships as troop transports and container ships during the Falklands. It really doesn’t matter if you achieve air and sea dominance.
I actually see the US being able to interrupt Chinese air-sea dominance in the Taiwan Straits for some time yet.
The US does have long range antiship missiles that would find ferries, troop transports and container ships worthy targets.
But there is no way the US could target thousands of fishing boats - which could be unloading supplies on Taiwanese beaches.
