Going to court is the standard, and usually the only, path for resolving disagreements that parties cannot easily resolve between themselves. Retaliating by putting the passenger on a no fly list deserves public shaming and pushback.

For example, a major grocery store can put people on a "do not come here again" list. But this is an easy way for a big business to hurt a person and should not be used for minor issues. I might see this "the business bans whoever it wants for any reason" as a legitimate defense, but not in a regulated business with high barrier to entry.
