I imagine it like this:
You send your goods to market. How do they actually get there?
Is it a caravan? Do some of your pop leave your country when goods go to the market? Do you send troops to help guard your goods while en route?
In order to recall some goods, you would need to answer these other questions as well. Then you would have to decide if you can break up your troops, or the pop, or the caravan.
Using the market just got 1000 times more complicated.
