I mean if rmts did use the system to launder money it would leave a visible paper trail. 100 mil for a bone chip sold by sjsjka akakak wouldn't look fishy to you?

Thinking about it now two systems would be redundant but done properly this could be a good thing. A sell now option would allow you to just get rid of stuff probably at a very low price for instant gil if undercutting wars was a problem.
