It took just three and a half weeks for the virus to spread throughout Germany, popping up in every district, and that's with limited testing, mostly confined to those showing (severe) symptoms.
With 80% showing no or mild symptoms, in reality the spread was faster, still.
That's how contagious it is.
Also, about 15% of cases develop symptoms so severe as to require hospitalization. Letting the spread happen without measures to "flatten the curve" results in case loads certain to overwhelm every healthcare system in the world. Morgues overflowing and no longer able to manage, healthcare workers falling ill, making life-and-death decisions on the fly, all kinds of necessary infrastructure running out, from gloves to ventilators to medication to chemicals for testing. That's when the whole thing comes crashing down, and also when those ill (not Covid-19) will no longer receive proper care, and that's when the death toll rises through the roof.
Flatten. The. Curve.
Make sure workers have to eat and a roof over their heads, make sure small businesses remain solvent, same for mid-sized businesses not able to secure a loan, freeze mortgages for a few weeks, get creative so as to ensure that the economy is ready to restart once that thing has blown over.
Playing off people against businesses is shameful, devastating really, and the consequences of a repetition of Tarp, saving the rich and leaving pretty much everyone else exposed, for the body politic I cannot even begin to contemplate.
