i feel like a lot of people taking issue with the lack of realisms in the game may also be guilty of a great many anti-real ideas about what would make it more realistic
it's been said in this very thread that precious metals like gold account for ~%2 of the total mass of the milky way
that sounds like not a whole lot, but consider
if you're really hungry, would you rather have %2 of a single slice of a personal pizza, or %2 of a full jumbo city block sized family heart attack pizza? (substitute pizza for a food you actually like if you don't like the current terms of this very serious hypothetical)
consider:
the total mass of the milky way is estimated to be between around 800 million and 4.5 billion times the mass of the sun
for a little perspective, all the celestial bodies in the solar system, excluding sol itself, account for only ~%.0014 of the mass of our solar system
all the planets, moons, dwarf planets, comets, asteroids, dust, all of it put together isn't even 1/10th of a percent of our solar systems total mass
and in that tiny little 14 ten-thousandths sliver, earth's mass, and all the resources ever used by life on earth for billions of years, doesn't even account for a quarter of a percent
%2 might sound pretty scarce, but the amount of precious metals consumed by humanity throughout our entire existence on earth, every coin, necklace, temple facade, electronic gadget, car, all of it put together might as well be a microscopic particle on a factory floor compared to what we'd have to consume in order for material scarcity to to be a thing for our hypothetical future interstellar meta-civilization
