Money can exchange for everything. Namely, money have all in one. But, this convenience owe to lose accuracy and strictness. For example, tree of fruit have many variety. But, money theory decide only one about tree of fruit is A. A can’t divide into other fruit. Other fruit have orange, apple, strawberry, a pear, pineapple, etc. Money can exchange everything, but money have no ability to divide into everything. Everything is decided only one is A like fruits. So, money have only same price, for example, 10 dollars can’t beyond value of 10 dollars. But, human health can produce more value of human health. So, money can’t buy human health.
