Reading the above post, and commenting from a safe distance, with no personal experience of the US coronavirus issue, I suspect the American concern about "rights" had at least something to do with the spread of coronavirus.
I also did a bit of research fairly early on, and it seems that 120 million people flew into the US in 2018. I assume a similar or higher figure would apply for 2020. That means that about 2.4 million people fly into the US in an average week.
A lot of those passengers would then have caught a connecting flight to another state, of which you have 50. So it's no surprise it spread so quickly and so widely.
However it seems to me that the tension between federal and state governments in the US means that it's a lot more difficult to enforce a uniform system of compliance.
In a less democratic country like China, the government could order cities and provinces into lockdown, and it would have been dangerous to disagree. We had lockdown ourselves, and the state of Victoria is still in fairly heavy lockdown mode.
But it's getting to the point for us in Australia that we are going to have to start easing up, or the economic consequences will be disastrous.
The Europeans for example seem to be moving towards an attitude of living with the virus rather than trying to defeat it outright.
Why aren't we seeing Europe lock down again in the face of another COVID-19 wave?
It wouldn't matter who was US President - he or she would be in a no-win situation.
