The "reality" of the situation is much more fundamental.
A FEUDAL HIERARCHY will always use FEAR to tighten its collective stranglehold on citizens.
A FEUDAL HIERARCHY will always use FEAR in order to con citizens into "voluntarily" giving up their constitutional rights.
The lockdown may or may not be based on "nothing".
But that's actually purely incidental (moot, red-herring).
Even (IFF) the "deadly" SARS-2 is "really real" (THEN) the government STILL has ZERO authority to force people to stay in their homes and or deny them the right to free assembly and or force them to wear protective clothing and or wash their hands.
There is ZERO authority for any of these "emergency" "measures".
This would be TRUE even if we were in the middle of a full blown ZOMBIE OUTBREAK.
