That's great, but also it's good to limit how much you enable them to act out those fantasies on your own end.
Sure, but if I made a city setting with legalized dog-fighting, even if those people were portrayed as evil it would be reasonable to assume that you could interact with them in a legal manner, and that if you give bad actors that avenue they will gleefully use it. The point is to think about your setting and avoid doing stuff that is easily turned into something problematic without modification. See my next paragraph for a real-life example.
I think there's more at play than just that here, but I think it should be considered how people will interact with things. I'm reminded that in Pathfinder Society for a while you could purchase a slave. That obviously did not go over well with a lot of people, but it was rules-legal.
