My point was that argument seems to be directly contradicted by precedence, as evidenced by the countless times in the history of our country that state and local governments have shut down businesses and restricted travel for health concerns and disasters. They continue to happen yearly for things like hurricanes and those orders are generally much more restrictive.
In the past, the courts have not agreed that the "rights" of those protesters were infringed upon. It really seems like the prevailing opinion of the courts is that the government can do whatever it wants if you can't prove that it isn't purely in the interest of public health.
People acting like these types of orders are unprecedented is confusing me.
@Turbo's article went over past examples much better than I could. The only example it gave of an overturned quarantine is one that was discriminatorily applied only against Chinese people. If anyone can provide a better example of an overturned case, it would be great to learn about.
