I think you need to put everything into perspective and understand the human mind and appreciate human differences.
We could be having this same conversation about houses, cars, jewellery, art, cuisine or about 2 million other things.
I don't understand elaborate weddings. I have friends who have spent $50k on a wedding ring, followed by $80k weddings that included elaborate floral displays, fireworks, full orchestras, and a troop of midgets to carry in the ring and release the doves.
I just don't understand why anyone would pay that for a ring and a wedding. Luckily, my wife doesn't understand it either. Whew. We had a very small wedding and a simple but cost effective ring and simply didn't invite all the annoying relatives that are outliers on the family tree and whom we would probably never see again, knock on wood. There were no midgets. No doves. No violins. We only invited my mother-in-law because my wife insisted (ok, I exaggerate - slightly).
Any person who is even remotely logical will tell you that spending tens of thousands of dollars on a wedding is, in objective economic terms, a completely irrational thing to do. But the folks who do spend gobs of money on a ring and a wedding will tell you that they are deriving pleasure from doing so that dwarfs the monetary outlay.
Every person ascribes a value to each dollar they have, and we only choose to spend it when the utility of what we are purchasing (measured in our own subjective terms) exceeds the utility to us (again, measured in our own subjective terms) of keeping that dollar. This calculation is highly personal and depends on the value each of us ascribes to various goods and services as compared to the value each of us places on keeping our money in our pocket.
So really, a pipe is just a wedding in disguise.
