I think the same is true for most drinks that you can buy ready-to-consume in small packaging. For me at least, the value is mostly in the production and supply chain that ensures the drink is created, bottled, and distributed to a phalanx of locations such that I can walk into any grocery or convenience store and be reasonably sure I can buy the drink I want in a single-serving container for a price I find acceptable. So I don't think the product cost of the liquid itself really factors into the equation. Or at least it shouldn't. I usually assume most of what I'm paying for the logistics that lead to the drink being available and ready to drink where and when I want it. I don't think the original comment was offensive, just that "it should probably be cheaper" misses the mark because for most drinks in this category, the price of ingredients shouldn't be a significant factor in determining its value to the consumer.
