This paragraph in the article is particularly humorous :
“For that matter, one could go whole hog and fix the value of both the kilogram and the dollar but float the value of time. You say you want to be paid $100 an hour. That’s fine by your boss. But he gets to decide how many minutes in the hour. Or how long the minute is. You know you’ll get a kilogram of meat for the price a kilogram of meat costs. But you won’t know how long you have to work to earn the money.”
I can’t wrap my brain around pork belly commodities being sold in Kilograms.
