> That 100% of the population would be prohibited from leaving their homes? What about food? What about medical emergencies? What about a house burning down or a tree falling on the roof? What if a watermain bursts?

Other countries actually addressed those questions. The most stringent example is china: They restricted everyone to their immediate neighborhood, then delivered food and other essential goods to each neighborhood in a centrally planned system. Medical emergencies were allowed to leave a neighborhood and drive to the nearest hospital.

Not pleasant, but it worked.
