Preventing the spread of a pandemic disease is one of the very few things that even I, a hardcore anti-statist, would have conceded that states can probably do more effectively than stateless systems. So the fact that USG is basically just... not... is pretty enlightening.
There are a lot of things a state can do in principle that they will never do in practice because that's not what states actually are. Counting on an amoral violent gang to solve coordination problems because it's a third party capable of coercing arbitration is pretty dumb
