>Entertaining a king is valuable, in the economic sense, but feeding and housing a poor is not.<
No, actually. The economic notion of value is subjective. Economic thought, despite popular perception, does not view value in purely monetary terms. Instead, value is seen as subjective: something is valuable because humans value it. Human desire is the very definition of what makes something valuable.
According to who? Googling "economic value" returns a litany of definitions in terms of money (or, more generally, exchange).
I don't deny that there is a notion of value apart from the economic one, in fact I would even go so far as to argue that the terms "economic value" (and "market value" etc) give markets entirely too much credit by suggesting that economic value and market value do a halfway decent job of approximating or approaching the philosophical notion of value, which is the term I'd ascribe to your definition and to general use of the word "value" without additional qualifiers.
Yes, it is often defined in terms of money. That is because if you actually value something you would be willing (but not neccessarily able!) to pay for it.
But let's not get bogged down in an untractable argument over the meaning of words. My point really boils down to: economics does concern itself with value which is different than the market value. They study the cases where the market value will refect people's true perferences, and when it will not.
