If we do nothing, New York's problems are eventually going to be Kansas' problems - only a matter of time. And with states competing for resources, Kansas could be hoarding supplies NY needs now, or Kansas could end up having no supplies when they need it. And neither New York's nor Kansas' governors can stop or mitigate the spread within the U.S. generally. Put simply, the Libertarian handbook doesn't have a good answer for a pandemic. So I disagree with your belief that this is merely a state or local problem. The Federal government has a role in testing/surveillance, ramping up production of needed medical supplies, and directing those resources as needed. Because all of that is needed to get us through this.
