The following points has been raised by many Gaians:

1. Sellers Will Increase Their Prices - AND WILL NOT EVENTUALLY LOWER THEM.
I've been Vending since before I can remember. And the market has always been the same. Once prices inflate, they never deflate a huge amount no matter what the gold sink. They inflate, they deflate slightly, then they inflate back up - higher than the original inflation.
Vendors are in it to make profit, they will simply add 2% to their prices before selling them.
BEFORE YOU SAY: "Well they'll lose MORE if they add 2% to their prices"
THINK: That's 2% they never would have seen anyway - they won't miss it, they still make their target profit. Which leads me to my second point
The idea that prices will rise by 2% (or even more) has one flaw:
if sellers can raise their prices by 2%, they can do it today, and do not need the listing fee as a justification.
Furthermore, let’s entertain the idea that sellers in the marketplace only want to get a certain price for their items, and this is the reasons prices now are lower than what they could be. The 2% fee will "force" them into raising prices by a bit more than 2%, just to stay where they were. Even then, any industrious marketplace participant can today buy the item for the price that satisfies current sellers, and still sell it for 2% more.
If it could happen, it would have already happened before the fee was introduced .
So will buyers bear the full implications of the listing fee?
No.
If that were true, all sellers now would get 2% less for their items. For 2% less, not all sellers will be willing to sell their items. With fewer items up for sale, the price will increase a little. It will not increase by 2%, and the previous paragraphs explained why. So actually, sellers and buyers will be sharing the costs of the listing fee.
A more technical explanations: draw a supply curve and a demand curve. Their intersection is the market price. Now draw a new supply curve, adjusted with tax. The new intersection between demand and supply, which is the new market price, did not change by the full 2%. This is because demand is not perfectly inelastic, and neither is supply.
