Couple of points, the US Constitution declares states cannot, w/o congressional consent, enter into compacts etc...
Interstate commerce clause, for once, may be applied properly.
Just because the POTUS gave states discretionary authority to declare appropriate levels of emergency, does not mean that he does not hold authority to change that delegation.
Finally, let the states move as they choose, and then use thier decision making as cause for any further complaint for monies to recover economically....

We’re sailing into unchartered waters. The courts have ruled that state legislatures, mayors, Indian tribes and sheriffs, etc. are sovereigns.
I imagine it will take a decade or more for the courts and legislatures to sort out who or what is sovereign over whom or what.
