The 10th Amendment, explained for Trump — Vox

For the most part I don't disagree, however, the first part of your summary is not entirely accurate. The states have independent autonomy in any specifically enumerated states right. If the right is specifically enumerated ad a federal right, all state laws are superceded. In the case where it is not enumerated, the Supreme Court has ruled that if there is a federal law it supercedes state law, but if there is none it falls to the state. If there are no laws, well that is a whole different topic. The CoVID-19 situation is one of those. None of the shutdowns are actual laws. I really don't know how that works.

Cpl Alex Moore States do have laws to enforce quarantines:

There’s a table by state with with the applicable law referenced.

CW4 Guy Butler and though those laws may be on the books. They are not being used in these cases. The information even mentions that these are being done by executive orders. My state, California, is being done by orders from the Governor, not the laws mentioned. That is the problem. At some point, somebody is going to sue because the reality is Presidential and Governor orders are not laws. The Quarantining laws do not allow for the oppression of guaranteed Constitutional rights. Don't get me wrong, I follow the orders, it is common sense but Constitutionally this seems to have severe problems and the President, contrary to his assertions, does not have absolute power over the states. The states also do not have absolute power over the citizens.
