I needed to reread it a few times but it's what I meant tho definately how I'd have said it. I'd have thot more along the lines of the first one google pups up: "...measure or quantity increment acceptable to or specified by the party offering to buy or sell." Bottom line is we need arbitrage/middlemen that can convert lotsizes that providers like into lotsizes that consumers want. imho if Zerohedge wants to outlaw arbitrage today then I'll expect him to try and outlaw the retail sector next.
