Exchange products based on the amount of time it takes to produce them
Heh, well, it does, in the sense that we measure value in "human hours", targeting for "time-well spent" as our community's KPI (here). However, trade happens not between "meters", but between actual objects and "ropes", in that sense, the "meter" is a bit of a neutral thing, so we don't do exchange on 0oo in "unit of measure" we do it in real currencies, but we express and display it in "h" (the meter" of all currencies. So, I'd say, you could say both "yes and no".
Does it relate to 0oo too? [Mindey]
Heh, that is so related to the idea of consumer price breakdown requirement. It may be unfair that someone with a machine who can produce millions of items of same quality goes to the same market to compete with handmade items, and people buying them without knowing the human-time estimate. If this human-time estimate were to be included into labels, like an ingredient (ingredients are often legally required to be included), then people would start realizing and adjusting certain social inequalities, like product pricing.
