Economically, if a person is willing to spend $5 on coffee then coffee is worth $5 to them. Trying to attach solid philosophical reasoning behind that may be a fun thought experiment but it's hardly the solved one your responses seem to imply that you think it is.
>any system that defines value in a way that doesn't allow for these people
wat
Hedonism defines pleasure as the primary and most intrinsic good so any system allowing it is just hedonism. WTF? How would any system acommodate competing theories? Fun thought experiment, sure.
>Economically
Usually it would go the other way, if coffee is worth something to me, I will be willing to pay that. You mess up simple logic, get your head straight.
Your subjective evidence is not convincing, even less as I was implying coffee had an addictive and hence behavioral conditioning effect, part of which comes from advertisement like yours, so stop it, will ya.
I take mine black. I admit it is an acquired taste, but oh what a glorious taste it is! Maybe you just had some bad coffee.
You know, for many, that's a completely irrelevant factor in their appreciation for coffee.
And by the way, I'm pretty sure it does quench thirst, seeing as it's 99% water.
If 99% water solution just has to satisfy thirst, then a 1% zyankali solution doesn't kill, is it? It's a bad comparison, because I really don't know what else coffee brew consists of exactly, but you probably don't either, so ... that pretty much wraps it up.
