Only for those who have no idea what a theory actually is.

There doesn't always have to be one "true" technique that somehow stands holier than the rest.

And no one ever said there had to be. What does that have to do with models? Models do not claim to be the "one true" anything.

Here is a clear-cut instance of a model:
Copernican Solar System Model
What physically in scientific theory is like that plastic and metal assembly? (Is it the ink markings on the paper, etc.?)

The model is what it is-- the model. Therefore, that is the answer to the question you pose here.

You can use the model to teach someone about the solar system, but there is little to no gain in merely producing or possessing the model.

Indeed, no one ever said that "possessing" a model was all you needed to use one effectively. Did they?
