I didn't say that. The OP argued "Actually this is bad because the cost per ton of carbon saved is higher than some other way to save carbon."
The original replyer pointed out that "ways to save carbon" are not necessarily fungible and there are other benefits to subsidized rail travel. The followon dismissal was to throw back and come up with a way to "price" those other benefits.
What I am objecting to is the entire chain of thinking that starts with trying to do simplistic, reductionist price comparisons and then refusing to consider other factors that don't fit in the pricing exercise.
