At least that's what I'm seeing from reading this thread. I'm not entirely sure that I understand everything as well as I should, and I'm automatically skeptical of value fixing schemes since none has ever worked in all of history, at least so far.
I'm not sure that's true, on reasonable definitions of "worked". Currency pegs (whether to other currencies or to commodities) don't last forever, but historically some have lasted quite a long time, and been very helpful to commerce while they did.
