The comic book "The Watchmen" was based upon a libertarian idea: that people will spontaneously act for the common good when presented with a sufficiently grave common threat, because it is in everyone's self-interest. They call this idea "enlightened self-interest", and they believe it is enlightened by the human capacity for rational, long-term, far-sighted thinking.
Of course, the events of the last two years have shown us that this is untrue, and it untrue for the most prosaic reason imaginable: people are dumb. When presented with a choice between personal convenience and the common good, a substantial fraction of the population will choose personal convenience, every single time.
Worse yet, not only will they ignore the common good to do so, but they will in fact rationalize this behaviour by dismissing the common threat.
The pandemic didn't just prove the author of "The Watchmen" wrong: it proved a central tenet of libertarianism to be wrong as well. People cannot be trusted to act upon "enlightened self-interest". They can only be trusted to act upon unenlightened, unintelligent, thoughtless, short-term, short-sighted self-interest. And yes, that includes businessmen.
