There's so much wrong with this.
1. Once again, you don't have any idea how death certificates. Covid is listed as the cause of death when it causes the chain of events which kills the patient. In the vast majority of cases, this chain of events is very clear. Without covid to start the chain, the patient would have lived.
2. Who cares if the average covid death age is higher then the higher average lifespan? Do you think old people are worth less than young people?
3. You do realize that the covid death numbers we have now is with mitigation measures like mask wearing, social distancing, limited lockdowns, hand washing, etc. ICU beds across the country are close to being full and hospitals are almost at capacity. If you just let people do whatever, the death rate will be worse. Significantly worse.
4. Covid gives people chronic, long lasting conditions even after you're infected. In fact, covid patients are at a higher risk foor 17 health conditions compared to the flu. The fact that covid kills a lot of people doesn't make covid a light virus.
