The market is not the only possible judge here. Anyway, I didn’t say anything about objectivity. Of course “reasonable” is subjective. But if we have some basic values, we can make objective judgements about what furthers those values and what doesn’t. For example, we could decide that it’s not conducive to an equitable society to allow single individuals to make and keep billions of dollars on some small number of trades. And in fact, that was the case for decades before Reagan cut the highest marginal tax rate from 70% to 28%, which directly led to staggering inequality today. Modifying what the original commenter said, there’s something fundamentally wrong with profiting massively on speculation with food.
