But perhaps if you really want to consider the problem, then just take a look at what China is building: missile destroyers, submarines, aircraft carriers and stealth fighters. If all these things are so worthless and could not fight and defeat China, then why is China spending so much money trying to exactly replicate those capabilities if the future is all drones all the time or whatever other internet sensation of the moment.Because: One of their best opening moves is a blockade of Taiwan, and that requires naval assets.
And because: There is such a thing as hedging your bets. No matter what anybody thinks, it is unwise to bet everything on your missile forces or new drones. You don't want to overcommit to one strategy or one way of waging war and later realize that you need to fall back on older means and methods. (As experienced by the Russians in 2022-2023.) So building a navy may be nothing more than a hedge against the possibility that other ways of making war won't work out.
But there's really no avoiding the fact that mobile launchers like the DF21/26/41 can launch a small LEO SAR constellation (i.e. just a few satellites) and a few ~10 minute contacts per day would provide enough targeting data to pinpoint any US surface fleet in the western Pacific. It's easy to see how a sufficient volume of missiles removes them from the board.
As an aside:
> If laser-equipped American destroyers
It's almost laughably easy to harden drones and missiles to high-power lasers. You can even retrofit old ones. Various different methods have been known since the 1970s. Lasers might work against trash-tier weapons and DJI drones, but the minute they become common on the battlefield countermeasures will become ubiquitous.
