Some countries, most notably S.Korea, were able to avoid a hard lockdown (malls and casinos stayed open) due to extensive early testing and enhanced case tracing/isolation. They continue to be mostly open, with their massive testing and monitoring, playing whack-a-mole with each new cluster outbreak of cases and deaths.
Most countries were unable or unwilling to go that route, so a full lockdown they imposed. This was done so the health care system doesn't get stressed and overwhelmed with this first peak of cases, avoiding unnecessary deaths. Also the pause gives us a chance to learn about it.
The tradeoff isn't between lives or the economy/businesses, it's between lives and lives.
Being a communicable disease, easily spread by air droplets, makes it fundamentally different from drug or cancer or smoking deaths - you and your neighbor's decisions can affect your, and everyone else's, health, and maybe death, in a very immediate way.
So has to be community wide effort, with decisions on how to fight it, by all of us together.
Seasonal flu they can reasonably predict and prepare for, but not this new virus, which is way more dangerous than the flu.
Covid-19 is twice as contagious as the flu, and about 40% of the transmission is done by folks showing no symptoms, for over a week.. .whereas with the flu, those folks usually home sick before they are at peak transmissability. .. and a lot less of them need hospitalisation compared to Covid-19.
Lockdowns slow the inevitable spread of a virus of such easy transmission, gives us time to cope and learn about the new thing - what therapeutic strategies to employ, which behavioral strategies like social distancing work, how antibodies and prior exposure might, or might not, work to protect one from re-infection - less deaths and disruptions until we know how to roll back the full lockdown, and wait to see if a vaccine might work..
