If people aren't working harder to offset the tolls then they're strictly poorer as a consequence of the toll.
not strictly. the pollution has gone down, for instance, reducing future health costs, and improving quality of life.
You can say that about any tax. Which makes it extremely unconvincing as an argument against any particular tax, since in the long term money not collected from tax A will be collected from tax B.
(And they have the option of not driving, too.)
