I'm afraid this excuse just doesn't cut it, Danny.  The whole idea and
rationale for the "free market" is that it *doesn't matter what producers
intend*.  No one producer can affect the price significantly, nor can
any *individual* producer significantly affect total output.  All the
*individual* farmer can decide is: given last year's prices, which I 
am likely to assume is the best estimate of next year's prices, is it
profitable for me to plant my crops or not?  Also given that I already
have enormous fixed investments in land, machinery,etc. is it worth it to
spend the variable costs of fertilizer, gasoline, pest control, etc.
in the risk of achieving a profit this year ( and at what level is it worth
spending for these variable costs?)
 
The individual farmer has no way of knowing what other farmers in the
country will decide on these things.  If he did he would leave farming
and make a killing in the futures market.  In most cases the decision
here for farmers will probably amount to: continue farming and try to
produce as much as possible, because no matter how much *I* as a farmer
produce it will not affect the overall price for what I produce.
Or two, leave farming altogether and produce nothing.
OR, the variant of two we are talking about right now: being *forced*
to leave farming by a foreclosure and, again, production of nothing.
 
These are the workings of the free market: the very fact that the
free market *system* produces certain results *regardless* of the
intentions of those involved is touted as one of its great benefits by
Adam Smith and its proponents since his day.  Adam Smith's use of
this argument was
to say that individual greed leads to improvement in the social welfare.
 
I find it curious that now to defend against one of the proven
theoretical deficiencies of the free market that suddenly all its premises
are abandoned and instead some sort of intentionality invoked!
If people could decide or *know* what the optimum level of production should
be then why do they need the free market?  Such ability to affect overall
production implies control over the market which the free market already
assumes does not exist.
 
Sorry, Danny.  You are caught in your own "cobweb of contradiction" in trying
to argue against the cobweb effect: either the free market assumes individual
producers cannot affect overall production *regardless* of their intentions
or it does not.  Please be consistent.

p.s. very nice exposition of the cobweb effect, tho.  Even if your 
rationalization of it was a contradiction. It is a pleasure debating you!
