You're missing the point.
If you charged a million dollars for every bag used then basically no one would use plastic bags. Or at least few enough people that the aggregate environmental impact would be negligable. As it turns out $5 or $10 would probably work as well as $1M.
The whole point is that it's totally impossible to come up with realistic estimates for something like plastic bag waste. So you set the prices high enough to disincentivize their use.
The purpose is the disincentive, not actually putting accurate prices on externalities. Confusing these two things is the source of the confusion in SilasX's original post.

If it is, then it's also totally impossible to show that plastic bags are harming the environment enough to make draconian regulation a net gain.
In other words, the real purpose of the regulation is an arbitrary exercise of power: some people just can't help telling other people what to do, and when those people get to write laws and regulations, this is what you get. "Saving the environment" is just the latest ad hoc justification.
