> Why do people pay exorbitant amounts for basically a few hours of photos during their wedding, given that a wedding might end up divorce?

That's about the worst example of people paying more for something than it is intrinsically worth that you could have come up with! People pay lots for wedding photographs because they want good photos, you're paying for an entire day of a skilled person's time - actually more because they usually edit the photos and produce some kind of photo book - and because there's high demand for wedding photographers.

People don't pay lots because of price speculation for their wedding photos!

A better example would be modern art, or maybe MTG cards.
