To the dude about deployed laser weapons - you might want to reread about them as well, especially their targets. Even the most basic ballistic missiles are out of scope, much less those at hypersonic speeds.
Your earlier claim was there were no viable fielded laser systems for any task at all, just tech demonstrators. I showed otherwise. Talking about ballistics and hypersonics, or even "hypersonics", is obvious goal post shifting from your earlier comment but OK fine.
The reality is those 2 types of missiles are going to be rarely used and can already be defeated by current AD in a carrier group or with current GBAD. Here is a article for instance about a US ship shooting down Iranian medium range ballistic anti ship missiles recently:

They're dangerous but they're not some unstoppable wonderwaffe with 100% effectiveness. Nor are they cheap or easy to produce (the exact opposite in fact, costs alone are borderline unfeasible and production rates are typically less than 10 month for instance for Russia's Kinzhal) so they can't be spammed endlessly or frequently.
The big worry the US and other countries have is swarms of cheap drones with mediocre flight characteristics but deadly explosive packages (ie. Shaheeds), or larger waves of cruise missiles (ie. Kh101, which have production rates of around 100-150 monthly by Russia vs thousands for Shaheeds) in conjuction with the drones, that are deployed with other missiles to saturate AD and cause attacks to get through. Or to cause reduction of AD when anti missile weapon stockpiles are expended and AD becomes ineffective for want of ammo from being forced to defend against the cheap and easy to produce drones constantly*. The 100KW Iron Beam, and other less powerful but still effective laser systems, are ideal for use against them in those types of scenarios since its "ammo" is effectively gas or diesel and they're powerful enough to do the job.
We could go into other stuff like why would Australia or Japan join war against China if China goes visiting Taiwan, but oh well...
The US has treaties with them at a minimum to use their ports in war + they're extremely unhappy with how China has been acting for a while. The current situation has been a rather tense one for at least the last few years at a minimum. Same goes for other countries where the US has bases to operate out of in that region. If you're ignorant of this then you probably shouldn't be talking at all about it.
