I fully understand why advertising companies would be opposed to this, it's in direct opposition to their value prop. As a consumer, though, I don't want anyone who is not the entity I'm interacting with to know anything about me.

I think you give too little credit to the intelligence of ad buyers. They can figure out if a web ad is working the same way they can figure out if a billboard ad is working.
I think super-precise attribution would actually kill the advertising industry. The uncertainty is what allows ad-buyers to purchase spots well below their value. The uncertainty is what leads to money being spread around and supporting the most things.
It's a little like insurance. If insurance companies could precisely target rates, you would end up paying basically exactly what your health care costs are and maybe a little more. Insurance works because of uncertainty and large pools of customers.
