You realize wide swaths of the global population use communal transportation in the form of trains, busses and subways? And then go to work in poorly ventilated factories or office buildings? I'm not sure what you intend as the solution other than nobody may ever leave the house again. Social distancing simply doesn't work when applied to everyday situations like this unless you find a way to get most people to opt out. Just working in the same office means a high risk of transmission despite whatever 1-3m distancing rule you want to instate.
