I never really thought of school as a place that was useful for education. The only reason I don't have a master's is because during my Bachelor's was the time I just had enough and realised I can learn just as much for free online.
But I don't want to undermine the value that school has anyway. School above all else teaches how to work as a community in a society. It gives us friendships and unlocks our emotions, prepares us for the travesty that is the real world.
If we're constantly protected in a lovely private school with a bunch of rich white kids or at home where we might take a break by going to our own little nesting bedroom, rather than, say, hiding in the toilets so that weird kid doesn't start talking to you, how else do we develop our interpersonal intelligence or create valuable connections academically, romantically or otherwise?
These are actual questions by the way, not rhetorical. I always imagined homeschooling to be somewhat tragic in its own subtle way
