Why Is Money Valuable?

Interestingly enough, the peculiar procedure of economic measurement is opposed to the methods of measurement in science. Indeed measurement in science is based on the impartiality of the measuring technician. Measuring by money is actually based on the bias of everyone involved. What is more, in science units of measurement are presumably stable, yet money as a standard of economic measurement is constantly changing value.
Before I discuss the instability of money, the following question should be answered: why money generally retains value despite many reasons for value variations, why we somehow expect money to be stable despite the knowledge that it is not?

The utility of a certain consumable commodity be it cattle or sheep skin when that commodity played the role of money was an understandable reason for that money to retain value. In the case of gold or paper money rarity, social convention or respect for the government which issued the money can be the reason behind the fact that such things can start playing the role of money but not yet the reason why that money will retain its value.
The actual reason for money to remain valuable is the fact that people want more of it and once they get it, they choose to hold it and not give it away easily.
