I don’t see the purpose of such thought experiments as being to model reality (we’ve already got a perfectly good actual reality for that), but to simplify it.
You seem to misunderstand what models are for. A model is not the actual thing—thus, we do not say, “Why did you build a scale model of the solar system—we have the actual solar system for that!”. Instead, models always leave something out—they abstract away the details we don’t think are important to simplify thinking about the problem.

Other than that, I agree.
