In Human Action, Mises makes the point that we study individuals because trying to understand economics from the primitives of physical forces is intractable. Presumably, it could be done with sufficient knowledge, but we lack that. In the same way, we can try to model organizations like Apple as their own entity with goals and such. Maybe that works well and maybe it doesn't. It's a practical question. We have no way of knowing if Apple really makes decisions or has experiences, but we each know our own experiences and extrapolate onto others like us the same quality.

I would push back on the equivocation of collective and state, but I more or less agree that the people you're describing are misguided. We're social animals and the state keeps emerging. That doesn't mean it's good, but it might mean we're stuck with it.
