"[B]y way of the causality that exists only in our perception."
You've already explained this to me a few times. This concept is still illogical to me, and made no better by bringing causality into it.
And maybe it's easy to draw a comparison to our folk-quantum-theory level knowledge, but what problems does Kant solve with quantum mechanics? I don't see value in choosing to perceive the value of a qubit more robustly. It's still just the result of a probability function.
