If you give parents absolute control over their kids on something as fundamental as education, the kids themselves live in a what you call a "totalitarian government". That is why the UN convention lists education as one of the basic rights for children.

I live in the US. And even though I don't agree with all the laws here, I respect them because that is what this society agreed too. Even though it makes this country, again according to your definition, a lot less free than Germany on plenty of issues. Except the right to homeschool.

Btw, I do prefer restrictions that are justified to protect myself and others. Like stop lights, or the right of way, or the fact that the people treating me at the hospital have to pass a medical exam to do that. By the law that is enforced by the government.

You can change that law in Germany if you want. You just have to convince enough people that your way is better. Good luck doing that. I won't support it, and I don't have to. That's the kind of freedom I like.
