It's not even clear you're correct by the apparent (if limited) support of your own argument. "Transmission" of some sort is certainly occurring when the work is given as input. It's probably even tenable to argue that a copy is created in the representation of the model.
You probably mean to argue something to the effect that dissemination by the model is the key threshold by which we'd recognize something like the current copyright law might fail to apply, the transformative nature of output being a key distinction. But some people have already shown that some outputs are much less transformative than others -- and even that's not the overall point, which is that this is a qualitative change much like those that gave birth to industrial-revolution copyright itself, and calls for a similar kind of renegotiation to protect the underlying ethics.
People should have a say in how the fruits of their labor are bargained for and used. Including into how machines and models that drive them are used. That's part of intentionally creating a society that's built for humans, including artists and poets.
