Commensuration seems like a very interesting concept. I would wager that sociologists could actually observe different sets of commensurate things by asking questions with respect to different units of value. E.G. -- asking participants if they are willing to trade a thing for dollars vs asking them if they are willing to trade a thing for, say, trips to europe. The units don't fundamentally change the relationship between the concepts but I would guess have a good chance of altering the way people respond to surveys. This non-associativity of commensuration seems like an example of a kind of valuation phenomenon that perhaps a two-dimensional pricing system could better approximate -- even in the presence of actuarial optimization ...
