What makes you think the market can't handle this without the government? When United did that, the video went viral, the public was outraged, and so many people canceled their United flights and/or voiced that they wouldn't fly with them anymore that they lost something like a billion dollars from their market cap in the matter of a day or two, and every airline in America publicly changed their policies to be more consumer friendly. HOW ON EARTH do you get a swifter, stiffer punishment than that? You don't need government for this! Completely unnecessary. The free market works so long as consumers are engaged enough to consume in accordance with their values.
