Wait, of course people are occasionally willing to work for below minimum wage! That's the whole point of having a law about it! If every single worker said "I will never work for below $x," you wouldn't need to set the minimum wage to $x by law - nobody would be employed at below $x. The whole reason for a law is that people are, in fact, willing to take jobs below minimum wage on occasion. Therefore the argument that a minimum wage law is good for poor workers does not rest on the idea that such a law matches their individual revealed preferences, and it takes into account that the law prevents them from being offered jobs which they would occasionally be willing to take. Engage with the actual argument for a minimum wage law, please, not some obviously false straw man.
