Its an entirely inappropriate response for existing diseases such as influenza too. When people ignore what could be flu and carry on with their lives, it contributes to epidemics that kill tends of thousands of people in a country like ours every so many years.
So you are focussing on very important stuff, but I would go further. The mistakes now are based on things we always get wrong, and have been encouraged to get wrong in normal times, the default response to flu is as inappropriate as the dangerous responses to Covid-19.
This is also deep in territory where the establishment, the mainstream, have disgusting double-standards and most people know it. This was demonstrated when a doctor in another country (possibly Australia or New Zealand, I forget), early in the pandemic, caused outrage when it turns out they had been at work treating patients for days despite having symptoms. There was a lot of outrage and empty statements about how we all know that healthcare professionals and others should not go to work when sick, which people would have found to be some kind of sick joke. Because we know that there is always pressure to say the right things but actually the pressure is to do the wrong things. Claims that the system and ethics/values always encouraged people in that situation to stay off work do not ring true to those who have been in that situation in normal times, the pressure has always been in the direction of going to work.
I hope, just like I did at the start of the pandemic, that at least all the focus on wide range of symptoms, disease severity and the large number of asymptomatic cases will at least shatter the common misconceptions about flu that haunt us every season, eg when people think it 'isnt proper flu' unless you are bedridden. Flu is just like Covid-19 in that symptoms actually cross the full spectrum, from none to critical illness and death. So 'man flu' assumptions are fit only for the bin.
