In case you guys don't know what's going on right now, this is the "Time-out" syndrome in full swing. There is a well-known, widely-used method of disciplining young children called "Time-out", it involves placing them in a select spot, asking them to stay there for a pre-determined amount of time and leaving them alone to their own devices as punishment.
Naturally, children are immature and often do not take kindly to punishment - they get off of the, say, chair they were supposed to sit on for whole 4 minutes and contest the decision. The parent is supposed to put the child back on the chair without getting into unnecessary discussions, regardless of how many times the child gets off it.
At first, there's the defiance stage - the child gets off the chair because it's "funny", it's rule-breaking so it's amusing. After it comes a much longer anger stage when the child realizes that the parent is being firm - this is when the child attempts to establish negotiations with the parent for whatever reason, even if just to say that the punishment is unfair or that it's unwilling to succumb to it. After a while though, the child gets tired or even uses some very basic logic to realize that it is being re-sat on the chair and each and every time the "timer" restarts. The harsh reality hits it - if it sat on the chair from the start, it would've been free by now. This is the stage where the child gradually cools off and accepts the punishment, and after the allotted time passes, the child knows perfectly well why it was sat on the chair. Not only that, it had time to reevaluate its priorities as well as draw conclusions - it now knows what happens when a transgression is made and will avoid making them in the future.
As you can see, Kirito is now in the negotiation stage. He's being re-sat on his Ban Chair by the staff and gets off every now and then to tell us that he can get off the chair at any given time and roam around... we already know that, nobody's chaining him to the chair.
It will take some time before the third stage kicks in, so as a responsible Forum user, I will refrain from further amusing Kirito with new posts that he could reply to, and I advice you to do the same.
