If escape pods were treated as commodities, then the pricing would get weird. For instance, you'd probably want to break it up by faction, so you have "Liberty Navy Escape Pod" and "Liberty Rogue Escape Pod". And then you'd price what the different factions would either pay for it, or what the reputation change would be. A Rogue pod would be wort a lot to either the Liberty Navy (capture), or the Liberty Rogues (rescue). But not worth much to the Golden Dragons.
Personally, I'd find it pretty annoying to have six different kinds of escape pods sitting in my cargo hold.
You could do "homogenous escape pod", but then all you could really do it sell it. Big deal.
Course, ejecting from YOUR OWN ship might be cool. Say you're aligned with the "good guys", and you eject surrounded by pirates. Well, you would be forced either to give up just about all of your stuff as ransom to get away, or you could keep most of your stuff, but be "impressed" into joining the pirate cause. Or, you know, reload your autosave
