I understand your point of view and I agree with what you are asking for.
Let's take a concrete example. Someone slips in your yard and files a claim for a redemption or benefit. I know you are talking about more significant amounts than that. If one says to the doctor that this is not personal information because it is a work product, I am afraid that the insurance company could turn to the treating physician and say that it is a work product. It is decriminalizing it in a sense, and it could be used in that way.
