How is it arbitrary?
As arbitrary as 6 feet. Why not 4 or 8? Have you seen any tests to justify those 6 feet? How about masks? Have you seen any numbers to justify why a fully vaccinated person still needs a mask? If so, what is the difference in the risk of infecting another person if I am wearing a mask vs if I am not?
The best you got is "from an overabundance of caution" - a line straight from somebody's rectum.
but now this comparison is ludicrous.
The difference is in the extent and the nature of the means of control but the mechanism and the "authority" are the same.
The textbook definition of arbitrary - no logic and no accountability.
and
but it has a lot of similarity with martial law in 1981 in terms of the restrictions and the arbitrary use of power.
A "democratic" Australia in 2021 and a "communist" Poland in 1981...the same restrictions and the same enforcement. How could it be?
