It's hard to blame people for wanting something that's so limited.
I don't have a problem paying a "premium" for something that I really want and is rare. After all, I have wanted a 20th Anniversary PS4 since they were announced and I ended up paying a hair over $1200 for one new/sealed. And that was bidding for it!
But there is a point where you have to take a step back, take a breath and think about what you are doing. Everyone puts their own value on things, but there is
no way in hell I would pay $50 (give or take) for a bottle of juice just because it says Nuka-Cola on it! What are you going to do with it? Drink it? Keep it? Drink it and just keep the bottle?
I've been known to keep the aluminum limited edition Mountain Dew bottles or the Halo 3 bottle, but I didn't pay fifty friggin' bucks for it! If you want a Fallout collectible because well, who doesn't? - buy an action figure, t-shirt, Funko figure, etc.
