At my school, no rules - or kids - had to be "broken". It was not supression of a behaviour, the behaviour just did not exist. If people behaved badly, the group was self-governing, making clear to the offender that their behaviour was "not cool" - and thus, they weren't. If you have a cultural problem that shows itself in bullying, fire the teachers. Also consider stopping adversarial school activities.
If these rules extends to life outside of school, I would be concerned more than relieved by rules 1 and 3. We should not normalise state-level control of our private gatherings by teaching freedom of association is somehow evil in children. It also would give a group of kids no way to sanction against antisocial behaviour by another kid (cheating in a game comes to mind).
That this has the thin varnish of "democratic debate" (which, let's be honest, will be quickly overruled if the kids decide the rules are stupid) only adds the additional aspect of showing in real-life how democracy is a scam that enforces things the powers to be like to happen while giving the impression it was a majority decision.
