As findeton said, science doesn't tell you what is good (after reading Nietsche I'm not comfortable using that word) or bad, just creates models that predict how nature will act. Using these models models to attain a specific aim is engineering. To chose these specific aims you need morals.
Since I don't believe in natural law nor absolute values, I feel imposing morals to others is wrong.
Money is not needed to survive, it's just needed to trade. If everybody valued goods and services the same way, we couldn't even trade.
If you reject trade, you have to chose between self sufficiency with no specialization nor division of labor or some people imposing values to others (kind of communism).
If you accept free trade, you have to chose between some form of money or barter as a tool for trading.
1) Do you believe that absolute values exist?
2) Do you reject free trade (and thus freedom)?
If you answer yes to one of these questions, you should put that at the beginning of all TZM materials so people like me could stop listening and don't waste their time.
