Please "if ppl understand" lulz. Don't be silly, people are people - if something is not outright forbidden and enforced - they will still do it and in case of Coronavirus - you don't even need a lot of those to begin with.
These lockdowns are in effect exactly because people did whatever the fuck they wanted - nobody slapped a lockdown outright, every government asked nicely to stay safe and reduce their outings as much as possible and you ended up with packed parks and beaches.
As a whole - these lockdowns are needed to catch up. Of course countries won't be staying locked for a year, it IS impossible, but a month or two to get up to speed with preparations and equipment for second wave? Yeah, can do.
