There is a strong "what were they thinking" behind this because we found out very early on that this virus didn't spread on surfaces, by spring 2020. But the public health apparatus found that keeping people as fearful as possible (even for irrational reasons) was useful for getting them to follow their guidelines. Double bonus for highly visible, borderline superstitious rituals like hand sanitizer, which helped identify those who were compliant from the dissidents such as myself.
I live outside of Boulder, and long, long after this was known, the businesses were still engaging in surface sanitization theater. My daughter's swim school had employees walking around with large devices, spraying fluid on every chair in between classes. This was going on all the way into 2022. I asked the employees if they knew that covid didn't spread on surfaces and that what they were doing was useless. They knew, but did it anyway because the owner "wanted to show customers they took covid seriously".
As a person who was demonized by my colleagues for not wearing a mask OUTSIDE on a windswept hiking trail, I'm frankly triggered by comments like this where people pretend like the information and data showing how irrational and panicked the social reaction was didn't exist. It did, and the people who were the most irrational, panicked, and aggressive towards those attempting to be rational are the ones making excuses like this.
There needs to be a reckoning on this insanity and the public health authorities who deliberately chose a "stop covid at any cost" strategy. "At any cost" is correct. They completely refused to do any form of cost/benefit analysis for the absurd panic they produced. I, like many on HN, had relatives who refused to leave their homes, and were wiping down boxes from Amazon for months. These were relatively young people with no health issues. There's a reason why the average American overestimated their likelihood of being hospitalized from covid by 50x, and that's the combination of public health and the overly compliant, ideologically blinded media in the western world.
