He stock for Void items seems to not have been bought out yet so there could be more in circulation. I imagine that more in circulation can decrease the price, the supply is the same for those who wish to buy at torishop price, so the increase in demand would make the price go up in the torishop if the prices can do this (I thought the prices stayed the same in the torishop right?). The supply of void items in the market would increase since the items which would otherwise be in stock in the torishop would now have flexible prices being sold by marketeers. This added competition to sell the items could reduce the price as it is less likely that everyone selling them will be patient enough to sell at the highest price possible and because only the cheapest items will get bought. The demand for the items for those who want to equip them is the same, so the only demand increase is among people who want to earn tc through marketing, I am not sure what this would do to the market price, perhaps once the stock sells out the prices would rise more but in effect this is just user selling to user so is entirely irrelevant to tc sinking and inflation as someone will of had to get the item from the torishop initially. In other words, more items to market and more tc spent on the torishop is good for everyone unless you have a load of high qi items you are waiting to sell (in the case of the prices dropping) or if you want to buy a high qi item to equip (in the case of the prices rising). More tc sunk and more marketing for marketers sounds thoroughly supportable to me.
