i mean, if you want to go all epistemological, sure, let me rephrase. each of us individual humans live in a specific world mapped on what we believe we know and our lived experience, and there is (at least) one unique world for each individual human. the price is a representative agent of a subset of the worlds that exist within the minds of the participants of the economy. as the mappings of reality upon the beliefs and experiences of the individual participants change, the price changes.
