I don't really think we disagree on the overall picture to be honest. I realize they're probably doing something (or I should say multiple things) right, and I realize the US has had organizational failures and such. I'm just not clear on what exactly having testing capability would let the US do that it otherwise cannot do right now, and I've yet to see a direct answer to this. If healthcare providers are saying that they'd just tell anyone who might have the disease stay home, then how does testing change the picture? Can't they do it already? Or is the idea that people would only obey this if they actually tested positive? And for tracing, can the US even use GPS etc. data the way South Korea can to trace their contacts, and invade people's privacy just like that? Would testing make that noticeably easier, compared to (I don't know, just thinking aloud) making medical providers report those that call about an illness so their contacts can be traced? etc.
