I am 100% against this. To start, the listing fee should have never been implemented for first time listings. It should only apply to a card being listed, after it had already been listed in the past X hours/days. Increasing it even further would be devastating in many ways. It encourages players to do deals outside the market, which increases the risk of scams.

I am ok with an increase of the listing fee for relisting, not for listing for the first time.
