Buying and selling pizza

I was wondering if the devs had any intention of setting up a pizza trade market so that players can sell the cash currency to other players for gold, a la Guild Wars 2.

 

That would be problematical in many ways.

 

I would be fine with it but a trade for items is much more important to me and i really think the game will need that to really thrive.

 

In what ways would that be?
