Even if everyone works from home, which many can, proper social-distancing leads to people not using cafes, restaurants, corner shops, taxis, no one will get anything non-essential done to their house, or go on holidays/trips or to their local clubs/events. Household economic footprints will shrink enormously. If most people do this for long enough, the economy is going right off a cliff. Probably already is in Northern Italy which is impacting the economy of mainland Europe.
It could easily happen here long enough for small businesses to go under and redundancies to start taking place on mass. Economic spiral becomes a self-fulfilling event. I worry that people are closing their eyes to this. The alternative is just to let the most vulnerable in society die and 'carry on'.
