I think that is the issue. Even if the homeschooling is completely online, you are saying that the socialization is now an extra demand placed on parents. We already saw how poorly most handled even getting their kids online for a Zoom or Google hangout. Teaching is incredibly hard work and I think we under value it. I think parents don't want this extra load and most have trouble even helping kids with homework and assignments they had specific instruction on.
In my experience (and ours are all different), school taught me a lot of lessons that had nothing to do with academics. There are good teachers and there are bad teachers (just like bosses). Sometimes you have to do work that is dumb or pointless just because that is the rule (just like work). I met kids richer than me and kids poorer than me. I met kids of other races and religions. You learn how to handle people calling you names and you learn heartbreak. Constant time together with friends you've had for years and shared lots of up/downs can't be quantified. I don't think you get the same exposure at a club that is likely socio-economically grouped and a couple of hours per week.
