much simpler is to attract us navy in a south china sea and taiwan trap and destroy it with powerful combined land (asbm hypersonic missiles, bombers and also fighters and drones from artificial islands) and sea (carriers submarines ddg drones etc) power. The trap is set.
This implies that the US would react in the manner you describe, and it also means that the PLA is okay with ceding strategic initiative as well as possessing no capability to project power outside of the second island chain.
Everyone (and I mean not only on this forum but also thinktanks and defense media) would benefit from thinking about PLA procurements in terms of what their own requirements are for a conflict. What is the actual level of risk and power balance that they would prefer to have for an actual conflict -- are they happy with having a high chance at victory at rolling a six on the dice only, or do they want the ability to have a high chance at victory even if they were to roll a one?
