You could approach it from a civil liberties angle. But if you're really interested in what would be best for the population overall, perhaps try and cite some data? It took me 5 minutes of Google searching to find some interesting results...

It was definitely good for them to hold that child in the basement! As a population overall.
Why would I care about "civil liberties" if they come at cost of ruining my life? And I know I'm not in any way an exception. I won't be around enjoying them, right? Do I look like a person who enjoys anything right now?
My meaning was this you can argue the following: That home schooling is a kind of basic human right. That there are some rights that a parent has to determine how their child is brought up.
I'm not making that argument. But I would be interested in hearing it. And hearing a justification for it.
Sounds like the Ursula K. Le Guin story is exploring individual versus group wellbeing. Thanks for posting it, I'll try and read it sometime.
On a personal note: I do know that school can be a horrible place. It can also be a huge time wasting exercise. I intensely disliked it. I'm sorry that you had a bad experience there, schooling can be particularly distressing because it's an experience forced upon you at a young age. I hope you are able to work through your problems.
A few weeks ago, at a local school (in Japan), a teacher beat a child in an after school class with a Kendo stick. The child was in hospital for a month. Very bad things happen at schools...
But... these are all single data points. And I honestly want to understand the wider picture.
I think that home schooling is a basic human right, just like choosing where to live and what job to take. That's because we are human and not ants. School for which there are no alternatives is a small Gulag camp.
I'd like to see more data, to better understand the situation.
