This is Utopian and within possible reach, although not so simplified (I’m thinking of short work weeks, free education, health-care, social security, etc). Many say it is impossible, but look at our progress from one generation ago. Many claim that human destiny is not egalitarian eudaimonia based on mechanization, but hierarchical eudaimonia based on human slavery (as futurists, we should get used to calling slavery the idea in which people work all day without even preventive healthcare offered to them, despite the luxury they contribute too by keeping luxury affordable. This is not their choice, contrary to conservative theory, but rather it is because of poor education and religious breeding doctrines–the real sinister side to it all is that the wealthy know they are slaves and the slaves do not).
Now about this money. Modern money is supposed to do basically how you described–a point system to enable or limit choices. Communism casually did away with money and created a disaster, because an appliance factory never knew when to increase production or stop it, there was no price to smooth out the supply and demand (money is an ancient institution, but tribal communism predates even this one, but alas, industry is modern, hence the need for money).
However, one fundamental difference between your concept of money is that it is used strictly in this way, and not as an incentive. Conservatives would howl at the idea of money not being an incentive, that’s what they live for and, damnit, that’s what they want you to live for too. So, to overcome this problem, we need to find a way to deal with their concerns, because they usually think utopia is impossible, even stupid, and they don’t buy into audaimonia either, that would be a religious realm to them.
I think I have an idea. We could have a two-tiered system, one with real money, the other with fake money. Everyone gets a choice of which one they want to use. If they use the real money, well, we could just pat them on the heads and give them everything they want and more. But if they use the fake money, we’ll have to discourage their purchase and try to sell them something cheaper and more practical–a reverse salesman! (“Oh no, Mrs. Grillbaker, you definitely don’t need another pair of shoes…Oh, Mr. Loudenrude, that little red sports car makes you look fat and ugly.”) Will that be real or fake money today, sir?
Sadly, eudaimonia has been demonized under our very noses for spiritual reasons. Drugs have been used by certain conservative interests to scotch the idea of common bliss unrelated to individuals or money, confusing it with drugs and communism. I claim that eudaimonia prevents drug use. I claim, proudly, that nature never provided for happiness through exploitation. In other words, if someone is starving and miserable in the world related to our actions, then we can never be happy, by definition. I also claim that utopia is the path of least resistance, as proven by modern democracy and progress, and we waste so much energy avoiding it, because, I believe, we don’t know how to enjoy it. We currently enjoy false status from others when they are deprived or beneath us in some way, but this is a self-deception of status. Now we know why the ancient Greeks admonished each other to “Know Thyself,” with “Nothing in Excess.”
