Wait... if we replaced money, what would we replace it with? The barter system? The honor code?
That question is only valid making different assumptions than I'm making.
Think of it this way:
There's a certain amount of "job work" that is done in our society. Imagine the sum total of all work. And I mean "work" in an economic sense, not a physics sens. Every piece of mail delivered by a mailman, every plate of food delivered by a waitress, every car that is manufactured, etc. Let us call this value X.
"Work" is not something that exists for the sake of itself. Work serves a particular purpose: to deliver goods or services to somebody. For every plate of food brought to a table by a waitress, there's somebody at that table who received the food. For every car that people work to manufacture, there's somebody else who received that car. The work itself has no value, and the fact of there "being jobs" is not the point. The point of "work" is to deliver goods or services to people.
Now, imagine a "hypothetical fantasy world" in which everyone had a magic djinni who instantly granted all their material wishes. I'm not seriously suggesting this...just, bear with me for purposes of discussion. In such a hypothetical world,
how much job work would need to be done?None. The value of X from above would be zero. There would be no point in anybody "working" because, again...the real purpose of "work" is to deliver goods and services to people. If anybody could just have their djinni give them whatever they want, there'd no point having somebody else build/deliver those things to them. And...because of this, there would
also be no point in having money, because money exists, basically, as means of inducing others to perform for you the work that you want to have performed.
Now...what if we reduce the amount of work required to produce the "sum total of all goods/services" required/desired by society? We might have a difficult time giving everyone a djinni, but we can very easily introduce labor-saving changes. For example, just as one arbitrary example, imagine if we switched to a flat tax rate. As a result, there would be no need for people to file long and complicated tax forms. Consequently, the "work" of preparing tax forms would be eliminated from the "sum total of all work that needs to be done by society." In this case, the value of X has been reduced. It is not made zero from this change, but it has been made
closer to zero.
Now, let's imagine that we...again, just an arbitrary example...switch completely from a centralized water distribution and purification system to a system where water is generated at point of use via
water condensers and houses use septic tanks rather than remote purification. This change would eliminate the "work" need for plumbing/sewage infrastructure construction and maintenance, sewage treatment plant construction and staffing and home bottled water delivery. And probably a couple other things. Yes, new work would be created because we'd have to build more condensers, but I'm confidant that the new work would be
much less than the work eliminated. Once again, X is made closer to zero.
Every time you reduce the amount of work that needs/is desired to be done, you reduce X, and make the world closer to the fantasy world where everybody has a djinni.
There are
lots of things that our society could do right now to reduce the value of X. Maybe we can't make it zero. We don't have djinnis. But we can make it
closer to zero. And there comes a certain point where it's close
enough to zero, that the need for a "work a job for money" system simply becomes pointless.
