That sounds really good and I'm sure the parents put a lot of effort into it but there's already such places where kids can go to do all those things.
They're called schools.
The social side effects of going to school are as important as the academic goals. Tell me which home schooled teenager learned to undo a bra strap with one hand? Got into a playground fight? Dropped water bombs on a teacher's head from the third floor? Turned a teacher's reliant robin over in the car park (only the uk ones will get that)? Got absolutely mortal on smuggled vodka during a chemistry lesson and had to be collected by very irate parents? Looking longingly at a girl you've fancied for 3 weeks and now know a love like no one ever has before you?
These are all rites of passage and to deny a child those experiences is a shame.
