The concept of freedom of movement was already thrown out during covid, as we learnt with the patriot act if you capitulate "Ok, just this one time because it's a special circumstance" then you lose that freedom forever.
Where was freedom of movement restricted in the United States? I heard of restrictions in other countries, but not here. I spent all of peak COVID in North Dakota and Minnesota, so I understand things were likely different in other places, but I don't remember hearing about any sort of travel bans within the country.
I’d guess at most a single digit number of people faced any enforcement consequences of violating stay-at-home in all of the USA. It was purely government performance art to say they were Doing Something.
I'm not arguing that this case is ok, though.
