I do agree it should have been done long ago.
But it's not some silver bullet. It will still take more work than it would deserve. It will just be a bit closer to how easy you guys have it.
I'm just using 'silver bullet' to describe it in the same way you'd say that penicillin's discovery was a silver bullet against bacterial infections, not that it's an immediate fix.
However speaking as someone who's done both sides of the mechanic, I can say that MA collection is a lot easier to do, which was why the numbers required was probably a lot higher as you can see below:
UA Collection
(i) Travel to system that is somewhere between 135-150ly (ish) off Merope.
(ii) Wait for RNG to give you a USS.
(iii) Pop in to USS.
(iv) If you're lucky it'll be a UA.
(v) Collect it
(vi) a: Pre Engineers run like a madman back to the station you're hitting. As long as you've got no more than 3 onboard, it can't burn through your cargo rack without the AFM stopping it.
(vi) b: Post Engineers, do as above but you can take your time, you can carry a maximum of 18t in a Annie allowing for shields and fuel scoop.
Ergo: One player can run between 3 and 18t of MA's safely per trip, depending on outfitting.
MA's
(i) Travel to barnacle site (which you can find from any reddit/cannon post regarding them).
(ii) Shoot barnacle. Scoop MA's and load into your ship.
(iii) Instance switch and repeat (ii) till fully loaded.
(iv) Return to your delivery point
Ergo: A trade cutter carrying 728t per run with a shield and a fuel scoop
