Nope. I completely admit to ignoring your question.
1. There are NPC owned facils on every race Homeworld. RM can be sold in them or in any of their ancillary buildings that are NPC owned.
2. To pick them up a person needs to submit a support ticket for an ASim to handle to get access.
Why this is NOT an issue:
Selling RM's to the NPC market is for the exact cost of RM's listed on the Rules page for mats, e.g. you aren't going to make any money doing so. You will LOSE money since it costs more than the listed price to get materials.
The NPC market is not designed for players to make money, it is a credit sink that is finally fixed. It isn't set for players to be able to sell stuff for profit, that is all player driven.
So only fools sell RM's to the NPC market. The few that do the buyer can get access from support tickets.
During dissolution's/deaths materials are located in whatever facils/ships/stations they were before. So then getting said materials is still firmly within the normal Player interactions, or you also bid on whatever the container of the mats is since it is probably up on the market as well :P
With rockivory being used for droid parts now, tis a simple thing to offer to sell an amount of it at a little above cost in bulk to someone who wants to produce a large amount of them which makes you something instead of a loss.
Still used so little I don't see any priority in changing the current system when there are so many other things needed for NPC scripting.
