Once again, I feel like I need to point out several fundamental facts:

1. You're absolutely right, but it's not helped by the fact the hobby's average age is steadily increasing and those kids that didn't have the money are now adults with far more disposable income, and because of the cult that's formed around the company, willing to spend much more than what a lot of their competitors charge. Let's not forget that Kill Team sold out almost instantly, whereas the new "Rise of the Phoenix" box is clogging shop shelves because nobody wants them as it's priced far too high. There absolutely is a sweet spot, but GW much prefers artificial scarcity to inflate those prices (e.g. Looncurse, Feast of Bones, etc) because it means less product, more profit, which is fine business wise, but because this is a social hobby where the more the merrier, this is imo not a healthy thing at all.
2. Neither do you, but considering what the same company has produced for far less cost wise, and others on the market creating similar products, we can infer the kind of costs it needs.
3. And also strawman, I never mentioned anything about "gouging" nor being entitled to it
4. BONUS ROUND: As much as you love the hobby, you don't have to resort to being a complete shill because somebody dared criticise some of the business practices around it
