I'm well aware of how markets work, but that doesn't make it less bonkers. Bottled water companies take municipal water, do some "filtering", and sell it for a 10x-100x markup. I'm sure the people buying the water thinks they're getting their money's worth, but that doesn't mean we can't point out how absurd it is, nor is " in most markets, price is a function of the value perceived by buyers and relative pricing of similar products" a satisfying counterargument to that.
