Only about half of those vehicles are actually in the game right now, too.
The thing is, with only one exception that I can think of, everything can be acquired in-game. The only reason you'd buy one of these ship packages is to have immediate access to those specific types of gameplay and, eventually, free in-game insurance (which otherwise also uses in-game currency). Sometimes these things make sense for player Orgs, but I can't imagine any Org needing all vehicles at all times... especially at that price.
As an Early Access, it has a LOT of jank; but it's unlike anything else that has ever existed. It really is a no-compromises, persistent, open, seamless sci-fi universe. It gets massive updates every 3 months, and those updates have been getting gradually bigger and more meaningful over the last 2 years. We've seen huge amounts of progress, so the developers are actually delivering. And regardless of how you feel about their business model as an outsider, it's successfully ensuring that progress can continue in perpetuity, which is exactly what all of us regular players want.
I skipped the original Kickstarter because even the smaller scope of that pitch seemed impossible on the budget they were asking. Then I watched the project for years as it seemed like it was falling apart. I didn't actually buy in until they showed off planet tech, and it was obvious that (1) they had finally gotten their development problems fixed and (2) their business model was capable of funding the project indefinitely (no matter how long it took to realize the vision). As of now, I have well over 1,000 hours in the game... probably more than anything else I've ever played.
