"Pricing it in" is a more specific implementation of "it's self-correcting." Where "it's self-correcting" could imply, among other things, that people will change their behavior. I'm not expecting people to change their behavior, but I am expecting that, over time, they filter out and shoot themselves in the foot, so to speak.
In the meantime, I am aware of the need to use external pressure to speed the process up. I'm not sure I buy the methods being proposed so far, but I understand the need.
Really good comments @inertia!
