Models are representations of reality. If you have the actual reality, as in all transactions for every product made by every agent, you don't need a model as you have the actual data. You can watch that in real time, and you can also test hypothesis and theories in real time. That in opposition to a model, say an economic model, which would be based on some theoretical assumptions attempting to predict supply and demand while looking at certain variables. If you have all the transactions that every single agent makes, as well as all social-economic variables about that person in real time, then any theory you have about their behavior can be tested in real time, rather than against a model, and validated or thrown away.

Models are representations of reality, rather than simple inference it's much more powerful to have actual data from reality available to test your theories, not just a model. Models are simplified versions of reality, a reality which is forever changing. Economic models are often wrong.
> Models are used to make decisions based on how things are expected to be years and decades into the future. It makes absolutely no sense to claim that you can tell how things will be in the immediate future if you're trying to make decisions based on what will happen over the following decades.
And this is why economics is often wrong. Knowing what is happening right now and responding to it, is much more powerful than making theoretical assumptions about how things are and then waiting and praying that they are right... which often they are not.
> The free market is just a specific theoretical definition of an economic system. It establishes conditions, draws relationships between factors and their effects, and provides a tool to model the evolution of economies.
I don't know which tools you are talking about. I don't know what evolution you are talking about.
One reason the free market is superior to central planners is exactly because central planners did not have actual market data but instead had to rely on models for supply and demand. When central planners have access to real time actual market demand as well as all data about each agent, it makes it much more likely that they will succeed at their job than the way the Soviet Union did it.
Also your tone stinks, work on that.
