Just my musings but could it be because if you broke lockdown rules in China you 'disappeared'? China did genuine lockdowns because they could, they even disinfected the streets during it. That was the only way a lockdown could work, the 'lockdown light' approach was never going to work as you, me and the more savvy among us continually pointed out - it was all or nothing and the west couldn't take the all in approach so massive fail.
