Money is fungible; time is not. Not all wealth is time. Thus it makes sense to trade time for money, and money for other forms of wealth.
But yes, ideally way you trade your time, i.e. the wealth you create with your productive time, should involve the things you want to do in life. But we are not always so lucky - and it is not always a good thing, as doing something for external reward can destroy intrinsic motivation.
