Which, imo, it kinda makes sense in an universe where gameplay moved waaay beyond making money.
See,
lots of people keep saying this like it makes exorbinant money spinners OK[1].
Realistically, it's just saying "credits don't matter"... and if that's the case the stuffit, let's remove credits from the game. Because if the "majority of the player base[2]" credit rewards from missions, exploration, standard trade, bounty hunting, war bonds and other mechanisms are going to remain dwarfed by a casual mining session, then they make no sense, and if mining is literally the only money making activity, then best get rid of it.
The hilarious part is all the other activities would still have their purpose in a creditless game, but mining would be totally out of luck. Either there's a sane and sensible progression to the earning of credits with the
rare and occasional windfall, or they might as well just not be in the game, because then they
are just a pointless grindwall.
"Credits are pointless, BUT DON'T YOU DARE TOUCH MY ENORMOUS CREDIT FAUCET" needs some major cognitive dissonance to comprehend.
[1] Not suggesting you necessarily think that, since I think I get your train of thought, just using the quote.
[2] Not that I think anywhere near the majority of the player base think this is bad, just the usual handful of vocals.
