Steve,
What exists? You seemed to think that qubits exist, but they don't. Qubits and binary digits are manmade concepts that people implement by using special physical setups, and utilising basic aspects of matter. Qubits and binary digits are not themselves basic aspects of the world. We are talking about what basic aspects of the world exist.
So, 1) what are the basic aspects of the real-world moving system?; and 2) what symbols do people use, or need to use, to represent the basic aspects of the real-world moving system?.
I think that, in order to more completely represent the real-world moving system, you only need the following types of symbols: symbols that represent categories (e.g. mass or relative position), symbols that represent relationships between the categories (i.e. equations), number symbols, and logical symbols.
There is nothing controversial in what I am saying, except for the issue of logical symbols. I.e., why are logical symbols necessary, and what aspects of the real-world moving system do logical symbols represent?
The fact is that, despite all the delta and other symbols, equations can only ever represent relationships, and not moving systems. Yet the real world is a moving system, and the fact is that only computer programs can represent moving systems.
Logical symbols, when used in logical statements, just like the algorithmic/ logical statements in the computer programs that drive computer systems, symbolically represent the system's knowledge of its time-place situations, and the system's movement in response to its knowledge of its time-place situations.
So I'm saying that, if you want to have a real-world moving system, you need real-world time-place aspects that are aware of/ know the time-place state of the system, and that move the system's numbers in response to this time-place awareness/ knowledge.
So these logical symbols, represent the basic time-place consciousness of the real-world moving system, and the basic time-place free agency of the real-world moving system. This is quite a different view to the views of those who, in order to preserve their outdated worldview, desperately cling to the mistaken belief that equations can represent a moving system.
Is that ontological enough for you?
I should add that, unlike the pre-determined deterministic law-of-nature relationships which seem to exist at a basic level, I'm saying that there are no pre-determined deterministic "logical relationships" that exist at a basic level, or any level. I'm saying that logical statements are our (human) way of describing the knowledge aspects and the free behaviour aspects of the real-world system or small parts of the real-world system. The "quantum" aspects of the system are the knowledge aspects of the system, and the free agency aspects of the system.
