It's about risk, and everyone in a free society should be allowed to assess the risk for themselves. After all, each person is in the best position to make that assessment because they have the most knowledge about their current situation. But people need good information in order to accurately make that assessment. People make risk assessments in their lives everyday. Everything from driving to sky diving - people take the risks because they evaluate the risk and decide the activity is worth it. This is why the one statistic that EVERYONE was interested in since the very beginning was death rate. Not overall infection numbers, not overall deaths - death rate.
People want some way to measure the risk. As we've been getting more information, it has become clearer and clearer (really not disputed at this point), that the death rate doesn't tick up until you get past 60/70 and/or you have some other aggravating condition. For just about everyone else, the risk is incredibly low.
