If there are people that do this stuff for free, you're disincentivizing makers.
I wouldn't want to be a taker in a market that consists of a handful known enthusiasts instead of a huge amount of anonymous people fighting to find a fair price.
What you're saying is you'd be happy to see fewer market makers and higher costs, so that you can feel good about it, as opposed to actual users being able to get proper service at a lower price.
