The 1905 case Jacobson v. Massachusetts supreme court ruled that communities have the right to protect themselves against an epidemic of disease that poses a great danger to their members. The disease of that time was smallpox. Small pox has nearly a 30% fatality rate and often leaves people who recover from it with permanent damage, including scaring and blindness. It is a "great danger" to the public.
Covid-19 by contrast, poses nearly no risk of death to healthy people and even the risk of death to people with underlying medical conditions is relatively low (6.5%). I've written an article called the Covid-19 media project that uses CDC data and a basic but medically consistent understanding of immunology to that the virus poses no risk of death to about 98% of the population. The article should be legally considered evidence that Covid-19 cannot be considered a great danger to the public and therefore there is no basis for states to impose restrictions to protect people from it.
In addition to establishing risk, the article also examines media articles to show why the misconceptions exist that Covid-19 is randomly deadly. The business model of the media is pretty simple, attract attention and sell advertising. The media made ever effort to exagerate the danger of the virus because in doing so, the story would attract more attention and developments on the story would continute to attract attention. Politicans responded to the public perception created by the media. Some politicians as the interests they represented were being harmed by the lock downs and public opinion began to shift as the public's interests were being harmed, change their positions. Other politicans who saw the exaggerated danger as being poliltically advantageous have maintained the virus is a great threat and randomly deadly.
One issue we have even after the lockdowns is public perception. As it stands now, probably 60% of the country is still under the impression that the virus is very dangerous. After the lockdowns many jobs lost are not going to come back in addition to small business who will not recover. Many sectors of the economy that provide goods and services that require people to be in close proximity to one another will continue to suffer and downsize. Once we win the legal battles to resume our lives, we still need to change public opinion to save our economy.

I have said all along that Trump needs his own broadcast company to give un-sensored real news from a conservative viewpoint. (truth) Sadly even about half of the leftists know that the MSM is 90% lies but they cling to it because it down plays Trumps accomplishments and conservative values. Being in my early 50s I have witnessed the downward spiral of society through teLIEvision programming. I could write a book about all I have seen and Im sure many of you out there could do the same.
Conservatives suffer from the same bias as liberals, where they accept opinions about subject they have very little understanding of as facts. Most issues are contrived and not important to the interests of most people in this country. Conservaties are just as responsible as liberals for giving credibility to the political entertainment theatre that creates the illusion that there is any real distinction between the parties. Rhetorically there is a great difference, but on policy both parties represent the business interests that position the candidates to be competitive in national elections. Trump does the same thing telling ridiculous lies and serving as a draw for attention to ensure people are focused on the new insane thing he tweeted or said. Apart from the sanctions on Venezuela and Iran, and his continued authorization of arms sales to Saudi Arabia, he has been very dovish on foreign policy, and I give him credit for that. http://orioncs.net/government-the-facilitator-of-money-to-power/
Trump is only a "liar" if you believe the MSM. There is your number one factoid. For instance if Trump were walking in the park and saw a burlap sack of puppies drowning in a pond and he rescued them, the MSM would report "Trump seen throwing wet burlap sack on the ground in city park". "Trump is littering and destroying our public places". Somehow he would also be called "racist", but I digress. That is the one sided, lying main stream media for you hence Trumps term "fake media". There is so much bias and hatred from the media , hollyweird , and brain dead citizens that buy into the BS from leftists.
For more on involuntary confinement, refer to:
O'Connor v Donaldson, 1975 - Court ruled involuntary confinement is a deprivation of liberty which the State cannot accomplish without due process of the law.
Foucha v Louisiana, 1992 - freedom from involuntary confinement is fundamental in nature.
Public Health Laws governing involuntary confinement for contagious diseases place the burden of proof on the government entity to provide "clear and convincing evidence" that an individual has or has actually been exposed to a contagious disease AND is likely to transmit the disease to other persons if not confined.
Stay at home isn't considered confinement and the cases you're citing are for arbitrarily detaining people for mental health reasons. Even if stay at home was confinement "the community has the right to protect itself against the epidemic of disease that threatens the safety of its members." Challenging the constitutionality requires showing the disease (covid-19) does not threaten the safety of the public and is shown very easily in the linked article Covid-19 Media Project.
