Duncan,
I think your "solution" still forces another assumption upon us.
Specifically, if gold producers capture absolute as well as
differential rent, we still would not know how much absolute rent
is involved. That is, absolute rent seems to be determined, in part,
by demand unless we assume that the marginal producer "sells"
gold at its value and has a lower composition of capital than
average.
