Not so fast....
First, you have a Supreme Court ruling (Jacobson v. Massachusetts) wherein it is was ruled that a state could take an action of this sort for the common good...and it doesn't have to be a law, it is ANY action by a state to restrict liberties for the good of the state. YOU have to prove that such an action is a HARMFUL to reverse it in the courts. Now the state cannot forcibly put a mask on your face....but the orders or laws that say you need to can still punish you.
Second, the 10th Amendment. In many cases where the plaintiff claims government over reach, the 10th Amendment which give the states power under certain circumstances is often used to sink the plaintiff's case. And again, it is NOT limited to law, but government orders.
Finally, you have to understand that because of the 10th Amendment, each state has a constitution that outlines these powers of the governor to give and enforce an executive order. Each state is different...there might some states that are closer to what you think should be the case, most others will not. Here is a link to these powers and checks by state:

On a personal note...such a sad sight to see so many men who are so-called patriots acting like Karens. Pathetic.
