Because I understand the word “simulation” to mean an algorithm which can answer questions about the states of the thing it simulates; not something which actually performs those same processes.
Yes, generally speaking. But certain kinds of simulation necessarily perform that which they simulate. For example, a perfect simulation of a scientific calculator necessarily is a scientific calculator, because in reporting what a scientific calculator would show as the answer, it necessarily itself shows that same answer.
The confusion doesn’t lie with me about this—nobody, not even you, has ANY problem understanding why the simulation of a physical phenomenon (e.g. gravity, flight, fire, weather patterns) is different to the physical phenomenon itself. And yet many people have trouble understanding why the simulation of a mental phenomenon may be different to the mental phenomenon itself.
Let’s re-word that last bit:

Certainly a Turing machine can be anything which is strictly defined by the return of an abstract output after the manipulation/transformation of a symbolic map it receives as input/initial state—so, a Turing machine can be a simulator, a calculator, a chess playing program, etc, etc.

Are mental phenomena are like calculations, or like physical event and processes? That is the question. You don’t seem to have answered it.
