I remember when I was a kid, I didn't really understand refrigerators. Like I knew that the cold would eventually leak out, so how was it cold inside if the cold would eventually leak out? How does insulation even work? So, I eventually figured it out. The insulation slows down the heat transfer. The fridge still has to do work to keep cold, but the insulation means that it can keep up with the losses and spend less energy on that. The countermeasures to COVID19 are like that. The virus is going to spread, but we still need to slow it down, so that the healthcare system can deal with individual cases, and not a flood. Some people are going to get it, but that doesn't mean we have to be fatalistic about it. We should take it seriously, but also rationally.
