"Farmers panic and say, well I better stock up while the price is still here. Maybe I can on-sell some later at higher prices if I need. Seller A says its $x. Buyer says great.

What you are describing is not speculation, it is forward ordering. Or do you have proof that there was wholsale onselling occuring? If you have let's see it. It would not be possible on a wholesale scale without a central echange.

Charging what the market will bear is the very essence of supply and demand.

"Do you know how trading works? Or do you need me to point you to an analyst's report for you to work it out?"

Yes I am a very successful trader, thanks for asking.
