It seems to make perfect sense. Its like storing and retrieving objects in a database. You can do it by hand, but its more of a pain -- better to leave it to something else and use the abstraction: storeData(key,value), retreiveData(key). We can directly map this to nice shirts. Normally one has to buy and iron shirts, which is a pain. (assuming you don't like buying or ironing). Now if you have a lot of money, you can pay someone to abstract that all away. You just look in your closet and grab whatever shirt you want. At the end of the day you just put it in the dirty clothes bin, and poof magically it will appear clean and ironed again in the closet. Money provides the person who abstracts the mechanisms that allow the shirt to exist. We could even do this experiment to harvesting the cotton, producing the shirt etc, which is abstracted away using money as trade for the various levels in the manufacturing.. mmm.
