“Everything that is really great and inspiring is created by the individual who can labor in freedom.”~~Albert Einstein
Every nation in the world attempts to regulate what can be sold and to tax economic activity. Because a physical object money (POM) is amoral, some of the uses of money will be immoral. Therefore the Church (of whatever faith) will attempt to control, to some degree, the use of money by its members. Parents don’t want their children buying certain things… or at least not until they are older.
Yet every nation has organized crime. Every congregation has members who sin to some degree in how they spend their money. Many children buy things their parents wish they wouldn’t.
Now you can say that using one’s money to buy what one pleases is freedom and should not be restricted. I would agree with you. But you will notice that the government with all the force of law and police and the military and the criminal justice system is unable to prevent organized crime. You will note that even with the power of the faith and Biblical support of their injunctions churches still are unable to prevent sinful purchases by their members. You have also noticed, if you are raising children, that even though they love you and you love them when they have money to spend you can’t prevent their spending it in ways you don’t like or want or permit.
The conclusion is that POM is uncontrollable. Unless and until all money exists only in computer accounts it cannot be controlled and, if it is still a POM, perhaps not even then because then there will be the powerful temptation to cheat. But do you really want the government to know every purchase by every citizen? Doesn’t that put quite a lot of power in the hands of those who run the government? So with a POM, either one has uncontrollable money (remember that POMs are also amoral) or one has an uncontrollable government. I will leave it to you to decide which you would prefer.
To be useful as a currency, any POM must be small enough and valuable enough to make secret payment for immoral actions possible and powerful. This is due to the nature of physical objects when used as money. No nation, no economy, no society, no church, and perhaps, no family can control how its members use a given currency, so long as it represents a tradable physical object.
