Of course! I think carbon taxes and the like are a great idea. If we had the social technology and the social consensus to enact pay-what-you-use schemes for everything, we might be close to a utilitarian utopia already. (For example, I have no idea how to compute the marginal benefit to an individual derived from living in a society that values egalitarian access to higher education, even if that individual does not choose to access those resources directly; but such would be necessary to pursue a rigorous calculation of that individual's fair share.)

Lacking that utopia, we have to estimate. You say income taxes are an unfair mechanism; what do you think is fairer?
