I'm not sure where you are picking up from. As with "anyone can do that." The only thing I remember talking about anybody "doing" is selling a car and giving the buyer money to take it. So in that point, you are going to have to be more clear.
Ok. My point was that for every transaction between two people, both must benefit from the transaction or there is no reason for the transaction to take place. Your rebuttal was that the seller could also get what he wanted from others. But that ability is a function of the overall system and not a factor in any individual transaction. In any isolated transaction, the seller gives up his goods/services in exchange for nothing, while the buyer gets the goods for nothing.
Though I will say this. People do need a little incentive. And you couldn't have some hobo going into a jewelry store and be given a lot of money to get the most expensive watch that they have.
. Why not? What difference does it make to the store?
Just as if everything were free, what anybody received would have to depend on a sort consumer index. Based on a person's value to society. So a doctor would be able to get things of a greater value than a hobo.
That completely changes your scenario. Now you are talking about an agency regulating who is allowed what and how much.
Next, money does play a role in this scenario. And it does serve a purpose. In what somebody would receive for "buying" some item. Or service. That is its use and its value.
Take money out of the equation. A person gives just his goods and receives just goods. What is the difference? Your money is just pieces of paper added on to giving away goods. No one gains any benefit from having money.
Next, it is a direct barter economy. Not in what they are willing to spend, but in what they are willing to receive.
No, a direct barter is when in any individual transaction, the two parties explicitly exchange goods and services. That’s not your scenario.
Also, ever see the movie THX1138? There was one part of the movie where a computer program told THX "Buy more. Buy more now." Under our capitalist consumerism driven economy, anybody who makes any product would probably love it for consumers to buy as many of those products as possible.
And the same applies for many services. Take car repair. It isn't unknown for mechanics to go down the highway and tell somebody driving an RV that they have some problem with it. When there is no problem. And direct them to the shop where they can get it repaired. I also had a friend who had a friend who worked as a mechanic at SEARS. Apparently he was told by his bosses that whenever he fixed anything to loosen something else up. So they would eventually have to come back to get that thing repaired.
And how does that relate to our discussion?
You also bring up communism. That would be something different. But I will say this about it. A long time ago I saw probably two different programs where they talked about how sparse items on shelves were in their grocery stores. Crowing about it showing the failure of communism. But maybe, just maybe, it wasn't due to there being a shortage of supply. Maybe it was because the average person was more able to afford whatever they had.
Both, actually. The State controlled wages and production without much regard for actual supply and demand. Normally, increased demand will raise prices to the point of equilibrium. But with set prices, people had plenty of money to spend, leading to shortages.
