Buffet's already done it for Delta beginning of March: https://www.foxbusiness.com/markets/buffett-coronavirus-batt...

I'm not assuming there will forever be lockdowns, quite the contrary, but for that there needs to be an effective system for responding to these kind of viruses so there doesn't have to be a full lockdown again. Basically you have to be able to quickly follow up on each case, and this will require things like determining where someone has been the past 10 days or so, and also regular controls (no more flying with any fever?)
