Yeah, being restricted by laws passed by random adults about what things you can and cannot do during school hours - such as being at school itself - is certainly characteristic of being a kid.

I don't think it's actually possible for a parent and community to safely and sanely raise a human child without some amount of coercion the kid doesn't want in the moment, so I don't advocate for this. Still, it is important to acknowledge that being coerced by people more powerful than you who think they know better than you do about what is good for you is unpleasant in and of itself, and society should try to minimize doing this to children to the extent possible.
