Were it not against his own interest to do so, Bart would grant you the freedom to leave your mutual disagreement at nothing more than that. Happens between individuals every day.

Unfortunately, Bart can't leave this issue at agreeing to disagree. That would mean the loss of his current job (or at least, having to perform the same job at the significantly lower rate he knows free people would pay for his currently overpriced (by government market distortion) service). So he asserts a right to power over you and airline operators, heavily against your will. And this is something he cannot deny; he can only attempt to convince you it is in your best interest (as he tries with everyone here). You appear to be smarter than that though, and good for you.
