Another reason people might stop producing things, or doing their jobs in general, would be a strike. If the Canadian truckers had all agreed to take a week or two off, instead of staging an occupation of downtown Ottawa, it's quite likely the government would have been forced to negotiate with them. In about 3 days, gas stations would be out of gas. In a week, grocery stores would be empty and peoples' vehicle gas tanks would be empty too. There would be a popular outcry for the government to get the truckers back on the road, and you can't just force 330,000 people back to work; there are only 65-70,000 cops in all of Canada. You can't arrest them; you can't commandeer their trucks (and they might all pull an important part out of the truck and hide it somewhere so it would not run until the part was put back in) because who would drive them? There's trucker shortages already, it's not like half a million people are waiting around to start driving trucks because Trudeau tells them to. So if people stop doing their jobs as a result of a general strike, there's a pretty decent chance the government is forced to negotiate.
