That is why your argument only works when you dilute the denominator into utter meaninglessness. We are talking about a large amphibious warship, a ship like the 075. There aren't many in the world like it. Wasp, America, that's it, and neither of them have VLS. Even when you include the next tier of smaller LHDs like Mistral, Canberra, Juan Carlos, and Dokdo, none of these ships have VLS either. You have to go all the way down to 8,000t or way out of class to aircraft carriers and DDHs to even find VLS, at which point the role of such systems in these ships is so far removed from what a 075's VLS would conceivably load that it makes little to no sense to compare them.
Hyuga and Izumo classes both have VLS. Just because some nations dont do a thing, doesnt mean others dont either. From what ive been seeing, the Chinese seem to be putting heavier defenses on thier capitol ships than most western nations seem to have.
