How do collector's items make sense with LTV?

I like to play MtG, and some of those cards are expensive as fuck, while others cost pennies, but they literally are all require equivalent amounts of labor. I also saw a Louis Vuitton dice case that costs $720. I'm no expert on dice cases, but I highly doubt it took significantly more labor than any other dice case I could buy at Walmart. Also how does artificial scarcity affect prices, and how does that work with LTV? Like, amiibos, for instance, iirc, are very expensive simply because Nintendo doesn't want to make very many.

TL;DR why come some things so expensive? Even if they use the exact same amount of labor as less expensive things?
