What I like about the author's idea is it is a technical solution to a technical problem. Taxes, incentives, or for that matter anything that requires large-scale public behavior change is: a) not likely to work b) equally unlikely to cause a change on the scale needed. c) will likely come with unpredictable and unwanted side effects caused by trying to force society to change (which is most often requires threats of violence and the loss of civil rights)
