Thing is Trump could end all this if he wanted to.
The 10th amendment does give states the right to call their own shots so as long as they don't violate the US Constitution. States do not have the right though to violate the construction. And if a state violates the US Constitution the president has the right to force them to follow the constitution and void any unconstitutionally laws.

Here's the 10th amendment


The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.


And these lockdowns and restrictions violate our 1st and 14th amendments and contact tracers violate our 4th and 5th amendments. Of course Trump won't do anything about it because he's just as much a NWO puppet as Obama and Biden.
