On the other side there may be one person that wants to have sex with prostitutes himself, another that believes women should be able to do what they want with their bodies, a third that believes prostitutes can be an important way for young men to gain sexual experience and skill, a fourth that thinks prostitution is bad but legalization to be a way of harm reduction.
Not all of these people may be willing to admit their reasoning in writing. You could say that only following the written down reasoning is a feature. I haven't thought a lot about that subject, so I haven't made up my mind on it.
I want my politicians speaking more honestly. Or at least having to write things on the record. Things in the system that pressure more honesty, accountability, and transparency are better.
They are not willing to admit it in any domain, which is exactly why we want it in writing.
It's called accountability.
What I would like to see is what harm it is supposed to prevent.
