Sounds okay, though I'm having trouble thinking of any reason why the Spire would outlaw any particular objects, rather than classes of objects. I suppose some "incites people to lawlessness" argument could be concocted. I dunno, somehow the CF legal system seems to be more no-nonsense and all about having a few very clear rules.

I guess what I'm saying is that the black market has to be put in a context, and the laws have to be modified to explain why you can get wanted for shopping there.
