I agree.
Home education can be the best way to go for some children, but (as in the US apparently) it has to be monitored, and criteria have to be met.
Just hoiking your child out of school and not teaching them anything worthwhile, achieves nothing.
Which is why (UK) we have built an education and health system that is still "Free at the point of need"
Yes, of course it's imperfect, underfunded, etc, etc.
Isn't any government run institution guilty of that?
But here are my thoughts.(Worth nothing, obviously!)

I'd rather have health and education run the way it is here (however rickety the system) than in other countries I could mention.
Back to the origins of this thread 800 pound fine for low school attendance? I'd make it 8000 pounds. (and a jail sentence for child abuse)
Let's just leave parenting to parents, and teaching to teachers.
And lets just hope that teachers and parents do their jobs correctly.
