I didn't say you could, pay closer attention or you will not be able to understand arguments or learn anything.

What I said was, "as long as people engaged in a market make their own choices, then money is a direct measure of happiness on the margin."

however, your mistake does contain a germ of reinforcement to what I said: if you cannot choose to participate in a transaction, you will be less happy, i.e. allowing sellers to offer choices and buyers to make choices will increase happiness in every type of market.

before you make another mistake and go shooting off, I didnt say people will be happy, I said they will be happier, but happier is an unmitigated good.
