The fact that you can buy any ship in the game with real world money at all is the problem.
These people are paying to remove that part of the game which blows my mind
Yeah for people who actually enjoy putting the work in it doesn't make much sense, but for some people who play video games it's not about the getting it's about the having. The problem is that in this case they can use real world money to have better stuff without having to work for it, giving them an advantage over other players who are poor or don't want to pay for their ships. If this was 48k for just ship skins and it didn't affect gameplay at all then it'd be pretty stupid still, but I would at least concede that the average person doesn't have any disadvantages if they only pay the 45$ for the main game and don't need to pay thousands of dollars to reasonably compete with players who have bigger wallets and less impulse control. But that doesn't seem to be the case here since different ships have different stats and abilities afaik. This essentially means that rich people (or gambling addicts which are their own can of worms) can unlock more of the game and perform better faster than people who only pay for the base game.
No ship should cost any real world money to buy. If the stuff you can buy in a game with real world money can give you an advantage over other players or unlock parts of the game faster than players who don't pay real money for it, then it's meaningless to say the game itself is "only 45$". The ships make up a huge chunk of the game and you can pay 48k to obtain them all immediately, or rather, not you because statistically speaking you're probably poor, so you don't get the same game for 45 dollars, not unless you want to spend a fucking loooooooooooooong time grinding in-game (based on what I've seen the time needed to grind for enough money to buy even one high class ship is ridiculous). Meanwhile richer players get to fly in circles around you in their better more expensive ships from the start. You get access to less of the game than them.
Also, 1.2k for a single video game spaceship in a game that hasn't even been officially released yet is disgustingly predatory enough on its own.
