As to #3, it's an opportunity to look at how a wide variety of governments deal with the situation--whether it be China or South Korea, Germany or the UK, the US or Iran. Many, many things to look at, and certainly a lot to consider.
In the US: when you have one party that for decades has professed to want a federal govt. small enough to drown in a bathtub, you've got to wonder how much that party actually wants the govt. to be successful. That is certainly in evidence when times are good, and now that there's a crisis that would benefit from leadership at the top, these folks seem to be scrambling to figure out what to do.
Does govt. need to do everything? No. I was reading today that S. Korea gathered industry leaders pretty much as soon as they had their first case and set them to work on developing and producing tests for the virus. Basically that's the equivalent of the "public-private partnership" that Trump was touting in the US--a month or so later.
Leadership, vision, coordination, communication--good things to see from your central govt. in a time of crisis. Wishful thinking, denial, delay, contradiction, and obfuscation--not so good.
