Gym in Melbourne recently fined for disobeying. Full force of government prosecution brought to bear to enfore a law that someone just made up.
Restaurants and gyms going out of business because no one wants to go there is a very different thing than being put out of business by government mandate. How long until "It's to everyone's benefit to prohibit drywall contractors roaming around, spreading disease, doing non-essential work."
Everyone's work is essential if they intend to afford food and not lose their house. Expecting these people to quietly accept being ruined is fucked. You could be next.
