A philosophical zombie can repeat all your thoughts about colors, so you can't prove even to yourself that you're not a zombie.

>But I know I do, and since physics relies on objective measurements that's a dead end.

You don't assume you understand all physics, do you? Objectivity in physics isn't the same as that of a layman: it has relativity, which proved many times to be counterintuitive.

>But we understand physics at the scale of the brain very well, and there just isn't any place for that binding to look.

What. We understand some physics at the scale of a neuron, but almost nothing at the scale of the brain. Ask anybody, inability to see any place is undoubtedly ignorance.
