OR, I have a better idea, why can't I sell the 80,000 pounds of platinum I have just sitting around on my ship?
To whom? What's the price for a kilogram of platinum on Omega? On Ilium? On the Citadel? What are the import tarriffs? Are you licensed to trade there? Do you need to be? What makes you so sure the ship carries ~230 tons of cargo - it seems more reasonable to assume they're a smaller measure than pounds?
This concept of "why are you there?", "what's the current value of x material?", "Am I licensed", etc, goes out the window when you're running around the galaxy strip mining planets(sometmes colonized ones) at your whim.
Alright, you asked for it, Ape's Theory On Rare Element Mining is go.
Obviously, scientific research requires raw materials, particularly if one is upgrading an entire armory at double-time without proper facilities. Equally obviously, Shepard isn't shopping for components every time the Normandy stops - you have mercs to shoot. An assumption can be made that Mordin, or one of the crew on his behalf, uses the Cerberus Gold Card (not connected to Shepard's expense account that he has to fill up himself) to stock up on vital materials on any hub or reasonably sized installation. However, these are the Terminus Systems (mostly) and you never stay still for long; some elements may simply not be available in the quantities necessary for Mordin's work - namely Element Zero, palladium, platinum, and iridium, as all of the above are used in the primary economy of the Terminus Systems, military hardware. Thus, in order to maintain the rate of advancement necessary, the SR-2 is going to have to locate these resources during its travel - either in isolated areas of inhabited worlds or pulled from barren ones.
Whether you prefer the probes to be auto-miners with a mass effect generator to 'fire' the materials back up to the Normandy or simply Cerberus-coded markers that let Shepard acquire these resources "on credit" from Cerberus-friendly sources (since he's marked the locations of replacement materials) is a matter of personal preference.
But it accounts for scanning while not turning you into a commodities trader.
