Sorry but your position contradicts itself and smacks of confirmation bias. If the US government really were systematically corrupt and authoritarian, why would they want to curtail economic activity? They would tell everyone not to worry about COVID and keep driving, eating out, shopping etc to maximize tax revenue and the availability of bribes.
I have read that many people believe outlandish conspiracy theories because humans have trouble accepting the reality that sometimes, bad things simply happen for no rational reason. It is easier for many to believe that a secret government cabal is conspiring to keep people in their homes than to accept that a deadly virus has infected millions of innocents and created massive global inconvenience.
