The reality is, of the 1/2 million or so, who will succumb to this deadly virus, a large percentage of those, would have died of regular influenza anyway.
What has been lost in all the calculations is the fact that all pandemics lose strength eventually, naturally. As they propogate, they tend to lose their inherent strength, intensity and effectiveness, as we witnessed with swine flu and SARS. These viruses are virtually, non-existent today.
This is a smooth-brained take if I've ever read one.
The death rate of "regular influenza" is estimated to be at 0.1%. We don't have full data on covid-19, but it's certainly higher. The IFR may be around 0.6% or 6x deadlier than the flu. The R0 value of covid-19 is estimated to by 5.7, meaning an infected person infects 5.7 other people on average. In the worst influenza outbreaks, the R0 value has never gone above 3. So covid-19 is spreading more rapidly, to more people, and is more deadly. This is, of course, without even getting to the onset of symptoms being more severe as well, which would factor into if "most of these people would have died from the regular flu anyway." Just wrong on all fronts.
I don't get the point of bringing up SARS. It had a lower R0 value (spread less easily) than covid-19 does. Also, patients were shedding the virus most several days after the onset of symptoms. COVID-19 (or SARS-CoV-2) patients are estimated to be shedding the virus most *before* the onset of symptoms. Isolation and lockdowns worked with the SARS outbreak (2002-2003) because it stopped the patients from spreading the virus even more - because it was easier to realize that symptoms = contagious. COVID-19 is being spread by asymptomatic people, rendering these partial lockdowns quite useless in terms of exterminating the virus. SARS didn't just magically get weaker - the lockdowns and isolation worked as designed.
The H1N1 R0 value was 1.46-1.75. H1N1 is also estimated to have killed 150k-575k people. It also didn't just magically end. The pandemic was finally over nearly a year after vaccines began to be administered.
So the two diseases you brought up are "non-existent today" because 1) their R0 values were much lower, 2) isolation and lockdowns actually worked because a patient was most contagious AFTER the onset of symptoms, and 3) a vaccine became widely available.
