As long as we cannot get things like emergency power cells out of our own stations - because of the old “only produced in X radius of Y place” concept - I’m not really for removing them. Because practically every surface construction (if not all of them) use(s) emergency power cells in their builds and as yet no alternative mechanics to hauling exist for progressing construction which could bypass that.
And I don’t think “Fly 500-1,000+ ly to Bubble” for each time you need that one commodity, or to leave a carrier stuck filled with thousands of them near colonization projects for a long time, is something that qualifies as ‘engaging gameplay’ or ‘well designed’.
