Lots of reasons, but here's one: Saturation of healthcare resources. People who get sick with Covid are more likely to use hospital beds and resources, and for longer as well. Also, as you get older the more health issues you will pick up, statistically speaking. So if at age 70, 60% of the population have serious health issues, something like 60% of the population is vulnerable. Saying 99% of fatalities had other serious health issues is almost the same as saying that older populations are more vulnerable.
