Humans, including kids, are inherently social creatures, and are happiest when communing with their fellow creatures (including pets, but mostly other humans). Kids are most happy when they and their friends are playing together, and my personal belief is that they are happiest when helping other people together (so much of my childhood play was around pretending being a hero, sacrificing and risking my life for the sake of others - what if that was channeled to real world aid).

That may be generally true, but it doesn’t imply that time alone is always bad, nor that all time “being social” is good. It’s certainly plausible that the explosion of access to social media has been a net negative and that spending some of that time alone would be better.
Thinking back, the time I spent having sneaked to the school library during lunch break definitely felt healthier than the times I got caught by a teacher and sent back to “socially commune” with my tormentors, er, classmates.
