The "deaths" aspect is a red herring in some ways.
People will get Covid19, this is pretty much unavoidable. Most people will not have a serious outcome. Those that do have a serious outcome require significant hospital resources to treat them. That's the important bit. If too many people are sick at the same time, we don't have the health resources to treat them given that treatment at the moment is limited to assisting patients whilst they try to fight off the infection. So the reason for social distancing etc is to try and avoid spreading Covid19 so that we don't overwhelm services, and people don't die due to lack of ventillators, beds, etc.
Many of the people who will die from Covid19 would have likely died from something else - Flu or respiratory infection. Many of those people are already very ill. Some people who will become seriously ill and may die from Covid19 were not particularly ill. So we try to protect as many people as possible by having sensible measures to try to ensure that spread remains slow and controlled until an effective treatment or vaccination is available.
You then have the balancing beam of increased issues due to social isolation, child abuse / child welfare where children are no longer seen in school every day and only remotely by health professionals. It's hard to balance.
And weren't some people posting that all pneumonia deaths were being counted as covid? This seems to contradict that.
It's a difficult balance. If you get Covid19 and it causes you to develop Pneumonia then did you die of Covid19 or Pneumonia? The answer would appear to be both, in that you may not have developed Pneumonia had you not contracted Covid19. But you can get Pneumonia as a development from a whole range of different respiratory infections. Hence most country comparisons focus on excess death rate over what is normally expected year on year.
