Physical laws are postulated to exist, and we make models that are proven and disproven by theory. Newtownian physics was replaced by relativity, which is being muddled by quantum physics. Physics is not cut and dried, so why should economics be? To use your own example, the market is made up of the actions of individual actors, who are each governed by underlying mental models/laws (such as a probability field around making a trade, etc.). The OP is trying to discover what those models/laws ARE.
