So you're okay with every single company being able to track you, build a profile to you, and sell that profile to the highest bidder, while you get nothing remotely comparable in value?
Not really. I have enough to worry about in the present rather than worry about imaginary future scenarios. I also think that since this is something most people are agreeing to, if it would turn really sour there would be enough of public outrage to make the worst of consequences illegal.
