That's exactly the thing where the fee works. If there is demand for your product, you know you can sell it at some point. YOu have to ensure that you sell it fast enough that the accumulated listening fees don't ruin your profits.
So people have to be more careful. Something on the exchange at a price of 50M might not sell for weeks, and the listening fee cuts what you effectively get for it. In some cases, you might not even be able to afford the listening fee and have to reduce the price.
This means there is an additional risk-reward consideration to make, and many people will work to reduce the risk if they can ensure a reward.
The people that got rich in the current economy can still try to sell their rare finds at premium prices. But they won't do that for long, if no one else can afford it and the listing fee destroys their EC.
