It's a fair point you bring up, but why should only people with kids be able to comment on this (which is unrelated to your main point to boot)? Sure, I can't have the same perspective as a parent, but if there is an experience familiar to everyone from minimally developed countries, it's school: we've all been to it. Even if we don't have kids ourselves we're exposed to family's and friends' kids, and we can extrapolate from our own experience what it might've been like to spend over a whole year being "in school" from our bedrooms and then another without natural human contact.
My nephew was surprised (and extatic) that the ladies in daycare are smiling once they took their masks off, it's obviously unhealthy to not be exposed to facial expressions while learning to be a social primate.
