Do all prices just reflect absence of information? In information economics, information has economic value because it allows an agent to make better decisions. For example if an agent needs to buy some good, he will benefit from knowing about the existence of all possible sellers since he will be able to buy at the lowest price.

I was wondering if there is work in economics that takes this view to the extreme and considers that the price of a good/service entirely reflects the absence of information about this good/service (to simplify it would be the sum of “not knowing how to efficiently manufacture this” + “not knowing where to get the raw material”)
It's a deeper discussion, but you could argue that profits reflect information disparities between agents.  However, in the most idealized circumstance, prices themselves arise from scarcity resulting from physical constraints of the system, not informational constraints.
