I didn't know that "states rights" was a libertarian position. Slavery was not libertarian, neither was Jim Crow. The 10th amendment must be interpreted in light of the 9th.
The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people.
Also every state has its own version of the bill of rights. Check out the Kentucky bill of rights.

Now the question comes, what should a free people do about an out of control state government? One is to appeal to the feds for relief. Good luck with that! The other is to ask smaller units of government to resist state tyranny. For instance there are sheriffs in Virginia who have vowed not to enforce the state's newly enacted gun control laws. But ultimately what happens in Kentucky is up to the people of Kentucky. How many have decided "enough is enough" and are willing to go against the lockdown? Who is willing to be like the salon owner in Texas who chose civil disobedience and jail rather than just sitting back and watching her children go hungry? A dictator can only be a dictator as long as the people propping him up allow him to be.
